1 Introduction

This report is a summary of the research activities and realisations of the members of our Centre during the 2007-2008 year. They will be described here, while the actual lengthy lists of publications and seminars will be made separately available. Usual warning: since the Centre is primarily devoted to research and the principal members all have faculty positions in the Physics Department, academic , teaching, funding and consulting activities are identical and will not be repeated here. Please consult the annual report of the Department for details.

2 Our Centre in 2007-2008

Subatomic physics is the field of fundamental research which addresses nothing less than the struc- ture of and its interactions. The four types of forces identified in nature are, presented here with examples: gravitational (planets), electromagnetic (light), strong (nuclei) and weak (radioac- tivity). The electromagnetic and weak forces have already been unified under the the , and now being completed by the strong force through the theory of quantum chromody- namics. Further promising unification efforts are currently being done to understand further the strong interaction and include gravitation. This highly challenging program is carried out experimentally by a few large international collab- orations. Our groups are involved in the foremost projects at research centers in the USA and Europe. The theory behind theses observations and much more are essential to our understanding of the physics, to sketch the way on how we should further proceed and to constantly develop new and imaginative ideas. Fascinatingly, it has be now been shown repeatedly that very high energy phenomena, in astro- physics or cosmology, are ultimately but other aspects of our research axes and therefore must also be investigated, both experimentally and theoretically. The orders of magnitude in scales and the complexity of the field lead to numerous scientific and technical ramifications, represent the unique characteristics of our Centre and strengthen its dynamics as a research entity. Our members use the Centre to deepen our research efforts, to create a stimulating environment for national and international research collaborations, to pursue recruitment and formation of young researchers and graduate students, and to coordinate all our common activities. This is being achieved through seminar series, conference and visitor programs, computer network unification, sharing of laboratories and equipment, extensive exchanges of experience and know-how, and devel- opment of applications. The “McGill Centre for High Energy Physics” has a 24-year long tradition, was already re-structured considerably in 1995 and underwent four years ago another transforma- tion as several new young faculty members joined our efforts and promoted new directions.

4 Research: Experimental High Energy Physics

4.1 Physics

Elementary particle physics is the investigation of the structure of matter and the forms of its interactions. Many theories and properties are left to the experimentalist to test and measure: the Standard Model, QCD, CP Violation, mechanism of top production, the existence of the Higgs and more.

The Standard Model

Decades of theoretical and experimental discoveries have lead to the Standard Model, which rep- resents our understanding of particle physics, its constituents and forms of interactions. It already unifies the electromagnetic, weak and forces. Actually, the electroweak sector was spectacularly verified in 1983 by the first direct observations of the heavy intermediate gauge .

QCD

Quantum Chromodynamics is the description of the strong interaction, yet including asymptotic freedom and confinement. Current experiments are very challenging to the QCD predictions because low energy phenomena cannot be calculated by perturbative methods. CHEP - Centre for High Energy Physics Report 2007–2008 9

CP Violation

CP violation phenomena have puzzled physicists for a long time and lead to amazing discoveries. It was shown that a third generation of would lead to large asymmetries which could then be observed in b- decays to test its mechanism. top production

The ”top” was the last missing basic constituent to be measured and superbly confirmed its expec- tation from the Standard Model. Detailed studies of its decay modes and properties will provide invaluable information.

The Higgs and more

The Standard Model still requires the Higgs to generate masses. It is expected that the Large Hadron Collider (at CERN) or the future Linear Collider will discover it and map its properties. But this can’t be the final story and the chances to come to grip with or to tap into new physics are very exciting to experimentalists. Experimental particle physics addresses all of the above concerns and maps them into the realm of international efforts in large collaborations of physicists around complex detectors. The McGill high energy groups are actively involved in some of those leading edge ventures: ATLAS, BaBar, CDF, DZero, ILC, SuperB, ZEUS.

4.2 Experimental Detectors at Colliders

ATLAS at CERN

The Large Hadron Collider (LHC) is currently under commissioning at the CERN laboratory near Geneva, Switzerland. It will collide at a centre-of-mass energy of 14 TeV, the highest collision energy ever achieved in laboratory. As such, the LHC offers a broad range of physics opportunities and enormous discovery potential. The ATLAS detector will record the results of these high energy collisions. Searches for new phenomena such as the existence of a , large extra dimensions, supersymmetric , etc. will be carried out. Many of the interesting physics questions at the LHC require high luminosity, and so the primary goal is to operate at high luminosity with a detector that provides as many signatures as possible using , gamma, , jet, and missing transverse energy measurements, as well as b-quark tagging. The variety of signatures is considered to be important in the high-rate environment of the LHC in order to achieve robust and redundant physics measurements with the ability of internal cross-check. The LHC offers a large range of physics opportunities, among which the origin of mass at the elec- troweak scale is a major focus of interest for ATLAS. The detector optimization is therefore guided by physics issues such as sensitivity to the largest possible Higgs mass range. Other important goals are the searches for heavy W- and Z-like objects, for supersymmetric particles, for compositeness of the fundamental , as well as the investigation of CP violation in B-decays, and detailed studies of the . The ability to cope well with a broad variety of possible physics processes is expected to maximize the detector’s potential for the discovery of new, unexpected physics. CHEP - Centre for High Energy Physics Report 2007–2008 10

Figure 1: The ATLAS Detector under Construction

BaBar at SLAC

For each particle of matter there exists an equivalent particle with opposite quantum characteristics, called an anti-particle. Particle and anti-particle pairs can be created by large accumulations of energy and, conversely, when a particle meets an anti-particle they annihilate with intense blasts of energy. At the time of the big-bang, the large accumulation of energy must have created an equal amount of particles and anti-particles. But in everyday life we do not encounter anti-particles. The question, therefore, is ”What has happened to the anti-particles?” is a High Energy Physics experiment located at the Stanford Linear Accelerator Center, near Stanford University, in California. The goal of the experiment is to study the violation of charge and parity (CP) symmetry in the decays of B . This violation manifests itself as different behaviour between particles and anti-particles and is the first step to explain the absence of anti-particles in everyday life. To study CP violation the BaBar experiment exploits the 9.1 GeV electron beam and the 3 GeV beam of the PEP-II accelerator. The two beams collide in the center of the experiment, producing mesons which decay into equal numbers of B and anti-B mesons. Thanks to the copious production of B-mesons, BaBar is testing the Standard Model description of CP violation. It will be able to over-constrain the CKM matrix Unitarity Triangle.

CDF at Fermilab

The CDF-II (Collider Detector at Fermilab) experiment at the Fermilab Tevatron records collisions from the world’s highest energy - interactions, with a centre-of-mass energy of near 2.0 TeV. Its position on the high-energy frontier of accelerator-based scientific inquiry is a striking feature of the Tevatron programme since, in the field of particle physics, the highest energies have proven to be an important provider of new discoveries in fundamental physics. CHEP - Centre for High Energy Physics Report 2007–2008 11

Figure 2: The BaBar Detector

Toward the end of the present decade, the 14-TeV Large Hadron Collider situated at the CERN laboratory in Geneva, Switzerland is expected to supersede the Tevatron’s position on the high- energy frontier. The next five years, therefore, are a unique opportunity for the CDF-II experiment to explore the heaviest known fundamental particles, such as the top quark, as well as the processes by which matter’s constituents derive their masses, the Higgs mechanism, for example. Results from the CDF-II research programme will play a driving role in defining the priorities of subsequent research at the Large Hadron Collider, which also collides against hadrons. Complementary to the energy frontier is the sensitivity frontier, another provider of new physics. In the 2.0-TeV collisions at the Tevatron, the production cross section is significantly greater than that at electron-positron machines. Although the background rates are also greater, selective triggering can amass high statistics samples with sufficiently high signal-to-noise ratios to probe rare processes. Unlike threshold machines, which produce mesons with either an up or down spectator quark, an advantage of the Tevatron is that it can produce all flavours of hadrons. CDF-II studies of these states will significantly advance our understanding of CP and flavour violation, as well as non- perturbative quantum chromodynamics.

DZero at Fermilab

The DZero Experiment consists of a worldwide collaboration of scientists conducting research on the fundamental nature of matter. The experiment is located at the world’s premier high-energy accelerator, the Tevatron Collider, at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, USA. The research is focused on precise studies of interactions of protons and at the highest available energies. It involves an intense search for subatomic clues that reveal the character of the building blocks of the universe The physics covered by the detector is very rich and encompasses: the top quark production and its mass determination, electroweak physics with the detailed properties of the intermediate W CHEP - Centre for High Energy Physics Report 2007–2008 12

Linear Collider Projects

The next generation accelerator will be an electron-positron machine, but in the linear acceleration mode where massive energy losses through synchrotron radiation are avoided and extremely high particle-on-particle energies reached. The signals for the elusive Higgs particles should be clear. The International Linear Collider (ILC) is intended to be an electron-positron linear collider pro- ducing collisions in the energy range 0.5-1 TeV. The ILC is widely acknowledged to be one of the highest priorities for the future of Particle Physics. Several fully developed proposals for such a ma- chine, have been put forward in recent years (e.g. TESLA at DESY). All regions of the world have now combined behind a common technology choice, based on the superconducting r.f. accelerating cavities of TESLA, and are carrying out a full technical design. The McGill group is a member of the CALICE collaboration, along with at the moment one other Canadian university group (Regina). CALICE is an umbrella for several R&D projects investigating high resolution calorimetry for a linear collider. The activities are focussed on a series of beam tests performed since 2005 in which a series of prototype calorimeter modules are being exposed to a variety of hadron and electron beams. The prototypes are all directed towards the construction of calorimeters with high granularity. As well as yielding information about various detector technologies, the beam tests play a crucial role in validating the Monte Carlo simulation programs which will be used to optimise the design of a full detector. In particular, simulations of hadronic shower processes in calorimeters are notoriously problematic, and good data are essential before credible simulation results can be delivered. The ILC will complement the LHC program very effectively. Whatever new discoveries may be CHEP - Centre for High Energy Physics Report 2007–2008 13

Figure 4: The DZero Detector made at LHC (the Higgs boson, supersymmetry etc), an electron-positron collider will be able to study the new physics with much smaller backgrounds and hence much greater precision. This will be crucial in establishing any theory beyond the present standard model. Many of the physics processes to be studied at such a machine require the measurement of the momenta of quarks, which will be detected as jets. The accurate measurement of the energy of a jet requires combining the measurements of different types of particles in different parts of the detector (tracking detectors and calorimeters). Experience from LEP tells us that good spatial resolution in the calorimetry is a crucial ingredient in combining all the information optimally. It is clear that an integrated approach to the detector design will be needed to achieve the best performance. The idea of a digital calorimeter with extremely high segmentation, combined with the use of new type of silicon-based sensor devices, is being investigated at McGill.

Super-B

The SuperB project is a proposal for a high-luminosity B-factory operating at the Upsilon(4S) resonance at an energy of 10.5 GeV. This project is a natural successor to the BABAR and Belle B Factory projects at the SLAC and KEK laboratories respectively, with a similar physics environment but with approximately 100 times more data. Over the past several years, a series of physics workshops have demonstrated that studies of B , charmed mesons and , all of which are copiously produced at a B factories, with extremely large data statistics can reveal, or provide interesting constraints on, possible ”new physics”, similar to that which is explored at the LHC at CERN. Moreover these studies remain interesting, and in fact potentially become more interesting, even if the LHC has already observed evidence of this same new physics. The complementarity and synergy with the LHC provides an very strong physics case for the SuperB project, however the project is still in the early R&D phase. In 2007, a Conceptual Design Report was submitted by the CHEP - Centre for High Energy Physics Report 2007–2008 14

Figure 5: The CALICE Calorimeter Prototype

SuperB group for international review. Additional physics studies and detector R&D activities are continuing, in anticipation of a request for a Technical Proposal for the project from the Frascati Laboratory. The McGill group has participated in studies of the physics potential of possible searches for various rare decays of B mesons. These decay modes are of interest because of their potential sensitivity to physics beyond the particle physics ”Standard Model”. The group has also contributed to conceptual-design activities for the SuperB detector and in particular to the impact of accelerator beam-background and radiation damage issues for the calorimeter.

ZEUS at DESY

The HERA accelerator at DESY, in Hamburg, Germany, is an electron-proton machine. The disparity of initial states and the asymmetry in the energies makes it an extremely challenging project, but extremely well suited for deep inelastic scattering measurements and QCD studies, 18 probing the content of the proton very close to the attometer (10− m!) scale. This enables us to determine the structure function of the proton over extended kinematic ranges, which is basically a description of its parton (quark and ) content. Ongoing detailed analyses of particle production also contribute to the understanding of fragmen- tation processes. production has been studied successfully by our group. Its aim is to probe the sea quark content of the proton and more specific details fo the fragmentation processes. Another projects are the observation of jets of particles: not only do jets testify of the quark and gluon content of the proton, but they also represent a powerful tool to determine the value of the αs coupling constant of the strong interaction. The available kinematic range in ZEUS is sufficiently large that the constant’s running can even be observed within this measurement. Photoproduction on proton, by which a quasi-real is exchanged, yields on the other hand a large amount of very relevant information on the many-sided and puzzling nature of the ¡it¿photon¡/it¿. Some of the observables are its behaviour, its direct interaction signals or evidences of its partonic structure. Via the observation of jets, I am interested in details of the hard processes, CHEP - Centre for High Energy Physics Report 2007–2008 15 which should provide essential informations on the photon parton densities. The data taking phase has been terminated in June 2007, but several analyses are still under way to extract the last physics results. They should be completed in the next 2-3 years.

4.3 Interdisciplinary Research

Particle Astrophysics - STACEE

The emerging area of particle astrophysics applies the techniques and methods of particle physics to problems in astrophysics. The McGill group was involved in STACEE, a project in ground-based gamma ray astrophysics. The experiment was using a modified solar-power facility in Albuquerque, New Mexico to provide a large mirror area for the detection of Cherenkov radiation coming from air showers created by high energy astrophysical gamma-rays. This experiment is now completed.

Particle Astrophysics - VERITAS

The Group has now has shifted its work to the VERITAS collaboration, building a new array of imaging telescopes for Cherenkov shower detection, at Mt. Hopkins in Arizona, which already have more sensitivity than the STACEE detector. Some of the most astounding recent discoveries about our universe have been made by telescopes and instruments collecting forms of natural radiation from space, that are invisible to the human eye. The VERITAS (Very Energetic Radiation Imaging Telescope Array System) telescope is an array of collectors that detect the small light flashes produced by high-energy gamma rays interacting in the upper atmosphere. Several sources of this high-energy radiation have been discovered with earlier pathfinder telescopes. These sources apparently exist both within our galaxy and in energetic extragalactic objects. VERITAS can detect much fainter and more distant objects than existing CHEP - Centre for High Energy Physics Report 2007–2008 16 telescopes, and is expected to discover many new sources of high-energy gamma rays. VERITAS is a collaboration of 10 institutions in the USA, Canada and Europe. VERITAS is the latest stage in the evolution of very-high-energy gamma-ray astronomy, a field where many aspects are closer to particle physics than to traditional astronomy. The basic idea is to use the Earth’s atmosphere as the ’front end’ of the detector, much like a calorimeter in a collider experiment. At high energies, gamma rays initiate extensive air showers in the upper atmosphere, and relativistic particles in these showers radiate Cherenkov that penetrate to ground level. An imaging detector located anywhere in the light pool can use the size and pattern of hits in its camera to reconstruct the energy and direction of the shower and, by extension, the primary particle that spawned it. This is the principle of the imaging atmospheric Cherenkov telescope (IACT). The effective area of the detector is the size of the light pool, which is of the order of 100,000 m2. The main background comes from charged cosmic rays, energetic protons and light nuclei, which typically outnumber gamma rays by a factor of more than 000. These can be rejected by using differences in the morphology of gamma-initiated and hadron-initiated showers that are manifest in the image at the camera Rs focal plane. Indeed, it is the cosmic-ray rejection power afforded by multiple views of the shower that has motivated the construction of the modern arrays of IACTs. In contrast to collider experiments, where data on different physics topics are accumulated simul- taneously with different triggers, telescopes are pointed instruments and a scheduling committee decides where they point. For the first two years of observations, VERITAS will spend half of the available hours on four Key Science Projects (KSPs). The remaining time will be given over to observations proposed by groups within the collaboration. One KSP is a survey of part of the Milky Way visible from the northern hemisphere, which will search for new sources with fluxes greater than about 5% of the Crab Nebula. Another KSP is an indirect search for dark matter. WIMPs could cluster in gravitational wells such as nearby dwarf galaxies or globular clusters and then annihilate, producing a continuum of gamma rays that may be strong enough to be seen by VERITAS. Although less direct than a search for supersymmetric particles at an accelerator, the gamma ray technique targets a larger range of candidate masses. Another KSP concerns galactic sources such as pulsar-wind nebulae and supernova remnants (SNRs), while yet another deals with extragalactic sources known as active galactic nuclei (AGNs). SNRs are interesting because they could possibly be the source of most galactic cosmic rays. With the new-generation detectors, their morphologies can be resolved and this will aid in the under- standing of particle acceleration models. Gamma rays from AGNs are thought to originate in their relativistic plasma jets, which are powered by accretion of host-galaxy material by a supermassive black hole. These sources are notoriously time-variable, so the plan is to conduct multi-wavelength campaigns using contemporaneous X-ray, optical and radio observations to uncover the physics processes at work in these high-energy objects.

Particle Physics Applications

Techniques and methods of particle physics are growing in scope and are making considerable impact in other fields, like medicine, astrophysics and cosmology. Particle physics has always pushed and stimulated developments of high technology, electronics and computing. Their effects are best seen in e.g. the establishment of the World Wide Web, open source methods of programming or innovative uses of special materials in detectors.

5 Research: Theoretical High Energy Physics

Our research interests are diverse, covering most of the active topics in high-energy theoretical physics. Here are some of the topics on which we have worked over the past few years.

5.1 Elementary Particle Physics

Elementary-particle phenomenology is the study of the properties of elementary particles as theo- retically predicted by the Standard Model, or by alternative models of physics at very high energies. The goal of such studies is to make the best contact with experimental results, in order to suggest the kinds of measurements which are most informative on key theoretical questions, or to interpret the theoretical implications of current experimental results.

Neutrino Physics

Recent measurements of properties appear to disagree with the predictions of the otherwise extremely successful Standard Model of particle interactions. This has stimulated a detailed re- examination of the relationship between the new experiments and older ones, and on how the Standard Model might be modified in order to take the newer results into account. We have studied: which neutrino properties are consistent with the various ongoing neutrino experiments; new types of signals within neutrinoless Double-Beta-Decay experiments; how interact with matter fluctuations in astrophysical media.

Precision Electroweak Physics

The Standard Model of the electroweak interactions is currently being tested in accelerator ex- periments to an accuracy of better than one percent. This permits a better determination of poorly-known quantities, like the mass of the as-yet-undiscovered Higgs boson. It also constrains the kinds of New Physics which one can entertain as replacements for the Standard Model at higher energies. We have developed: effective-lagrangian techniques for efficiently identifying how ‘new’ physics can appear within well-measured observables; the application of these techniques to identify which kinds of experiments are sensitive to which kinds of new physics. CHEP - Centre for High Energy Physics Report 2007–2008 18

Strong Interactions

It has been notoriously difficult to unravel the predictions of Quantum Chromodynamics (QCD), which is currently understood within the Standard Model as the theory of the strong interactions. The obstacle lies in the difficulty of the calculations which are required in order to make these predictions. In recent years several new techniques have emerged from unexpected places. We have helped develop these new calculational techniques: string-theory-based techniques for efficiently computing loop amplitudes in QCD; methods for summing infrared-singular amplitudes for soft- gluon emission.

5.2 Field Theory

Quantum Field Theory has emerged as the theoretical framework within which all physical theories are couched. The intricate consistency issues which must be satisfied by any viable quantum field theory turn out to very usefully constrain the theoretical possibilities at extremely high energies, where gravity starts to play an important role at the quantum level. The emergence of string theory as the only known consistent solution to these constraints has initiated considerable progress in understanding very-high-energy physics, even in the absence of direct experimental information. Our research in this area has included the following topics:

Black Holes

Black Holes are a frontier between known and new physics, since uncontrolled gravitational collapse relentlessly drives a system into a poorly-understood strong-curvature, high-energy regime starting from the well-understood regime of weak fields and low energies. We have: computed string-theory corrections to and dualities amongst black hole spacetimes; evaluated strong-curvature corrections to black-hole entropy; calculated the properties of the photosphere which develops around evapo- rating black holes.

Duality

Duality is the blanket name which describes the many surprising equivalences which have been discovered amongst apparently unrelated field and string theories. These relationships have revo- lutionized the current view of extremely-high-energy physics by showing that the many different string theories are duals of one another within a more fundamental framework, known as M-Theory. (Don’t ask what ‘M’ stands for.) Our research involves: the discovery and exploration of the con- nection between duality and bosonization; the use of duality to construct new solutions to the string equations of motion; the discovery of a new class of superdualities.

Supersymmetry

Supersymmetry is a beautiful symmetry which arises in many proposals (including,in particu- lar, in string theory) for the ultimate replacement for the currently-successful Standard Model of fundamental interactions. Our work includes: the runaway- problem in strongly-coupled supersymmetric theories; the viability of supersymmetric models for electroweak baryogenesis. CHEP - Centre for High Energy Physics Report 2007–2008 19

String Theory

String theory (or M theory) is the best candidate for the theory which unifies all interactions, including gravity. Within this framework the basic building block of all matter consists of extremely short, infinitesimally-thin one-dimensional strings, rather than the traditional indivisible point particles. Our interests in this area include: higher-dimensional D-brane solutions to the low-energy string equations of motion; the duality between string theories and four-dimensional conformal field theories; the relevance of string theory for the problem of information loss in black holes.

Inflation and String Theory

Inflation and string theory address the most fundamental questions of cosmology and elementary particle theory, respectively. Inflation replaces our old conception of the singular with rapid expansion of empty space, followed by reheating of the universe when it was already quite large. String theory replaces the old idea of singular point-like particles by extended, string-like objects, and achieves the long-sought reconciliation of quantum mechanics and gravity. Each theory by itself overcomes very serious problems within the old paradigms. But the new theories also come with their own problems. Inflation suffers from an embarrassment of riches: it is too easy to construct particle physics models of inflation, and we currently do not have enough experimental discrimination to distinguish between different underlying theories. String theory suffers from its lack of testability in laboratory experiments. It is therefore exciting that inflation and string theory can combine to benefit each other. String theory, being much more highly constrained than field theory, removes much of the arbitrariness from inflationary model building while at the same time offering new mechanisms for inflation. Inflation provides string theory with new observational constraints and signatures, making it more testable. It is for these reasons that string theorists and cosmologists have joined forces in recent years, in this fertile cross-disciplinary endeavor. One of the most exciting predictions of a certain type of inflation is that cosmologically-large strings could be produced as relics of the collision. Such cosmic superstrings could possibly be observed by their contribution to fluctuations of the cosmic microwave background (CMB), or by gravitationally lensing background galaxies. This is related to the larger question of how reheating takes place at the end of brane-antibrane inflation. Members of our team have been among the first to confront some of the important issues for the formation of defects and for reheating in these models. Although inflation does a good job of explaining the homogeneity, isotropy and flatness of the universe, and the nature of the CMB fluctuations, it is not yet a fully proven theory. It is important to test whether alternatives to inflation can be developed, and some of us have been using ideas from string theory, namely string and brane gas cosmology to do just that.

5.3 Theoretical Cosmology

Inflationary Cosmology

The inflationary universe scenario proposed in 1981 by Guth has provided a theory of the origin for the small density fluctuations which can be measured in cosmic microwave background tem- perature maps and in galaxy redshift surveys. The original predictions for observables have been spectacularly confirmed in recent experiments. Research at McGill focuses on further developments of the inflationary scenario, with particular emphasis on the study of the conceptual problems of the inflationary paradigm. CHEP - Centre for High Energy Physics Report 2007–2008 20

Theory of Cosmological Perturbations

Fundamental physics connects to observations through the detailed study of the cosmological fluc- tuations (density perturbations and gravitational waves) which are produced in the early Universe and propagate through time to produce the present observational signatures. Past work of the McGill researchers has played an important role in the development of the classical and quan- tum theory of linearized fluctuations. Current research focuses on higher order effects such as cosmological back-reaction, and on extensions of the formalism to brane world .

Superstring Cosmology

The inflationary universe scenario does not eliminate cosmological singularities, nor does it address the question of why only three of the nine or ten spatial dimensions of string or M theory are macroscopic. Research at McGill focuses on ‘string gas cosmology’, an approach to string cosmology which addresses these questions. Studies of cyclic cosmologies in the context of string cosmology are also in progress.

Baryogenesis

The study of novel mechanisms of cosmological baryogenesis is another key aspect of cosmology research at McGill.

6 Research: Experimental and Theoretical Nuclear Energy Physics

6.1 Experimental Nuclear Energy Physics

The current research programs in Experimental Nuclear Physics at McGill include the investigation of nucleus-nucleus collisions at ultrarelativistic energies, the study of nuclear ground state properties of unstable nuclei, and the use of nuclear techniques in applied physics. Most of the experiments in both areas are being performed as international collaborations at major accelerator centers in Europe, the U.S.A. and Canada. However, a great deal of the experimental planning and equipment design, preparation and assembly are carried out at McGill. The primary goal of the study of nucleus-nucleus collisions at relativistic energies is the study of the equation of state of hot hadronic matter and the phase transition to the new phase of matter, the quark gluon plasma. Our research program has now moved to RHIC energy where our present effort is on the understanding of the evolution of some experimental observables as the beam energy is increased to the energy that are now available at this new heavy-ion collider. One of our present works is a comparison between model predictions and the new data to help determine the observables that provide the best signature for new physics at RHIC. One of our studies aims at understanding the importance of hard process at RHIC energies including the quenching effect of nuclear matter on the propagation of jets. Our team is involved in the OSCAR working group a collaboration that addresses the lack of standards, documentation and accessibility in transport codes used to described heavy-ion collisions at relativistic energies. We contribute in the development of this standard and test the implementation of some new physics in the models relevant to RHIC, in particular, hard physics related to perturbative QCD. In the last two years, an important effort has been devoted to the development of a new version (v2.0) of the HIJING/BB CHEP - Centre for High Energy Physics Report 2007–2008 21

Monte Carlo nuclear collision event generator in order, in particular, to explore further the possible role of junctions loops in the baryon/meson anomaly observed at moderate pt in heavy-ion reactions at RHIC energy. Recently this new code has been used to demonstrate the presence of an increase strong color field in the dense nuclear matter produced in high-energy heavy-ion collisions. Nuclear ground state properties such as spin, electromagnetic moments and charge radius of ra- dioactive nuclei are basic properties of the nucleus which serve as important tests of our under- standing of the nuclear models and determined also the main decay properties of radioactive nuclei. In highly unstable nuclei far from the valley of stability, laser spectroscopy techniques can be used to measured these properties. These techniques are based on the precise measurements of atomic hyperfine structure in the interaction between the laser beam and the radioactive . In recent years, the McGill group has pioneered in the development of a number of high sensitivity techniques for these studies. At McGill, an apparatus for laser spectroscopic studies of ions stored in an RFQ (Radio-Frequency Quadrupole) trap allows the investigation of relatively long-lived isotopes. Work is also being carried out at the on-line isotope separator facility (ISOLDE) at CERN using collinear and resonant ionization spectroscopic methods, within an international collaboration. Other experimental projects concern Ion trapping techniques for nuclear mass measurements, Ap- plied Physics and instrumentation, ultrasensitive detection of trace materials, and radiation damage in silicon devices.

6.2 Laser Spectroscopy for Nuclear Studies

We investigate the fundamental nuclear properties, and specifically masses and radii. The work involves laser spectroscopy experiments for the determination of changes in nuclear charge radii over long isotopic chains as well as nuclear mass measurements using Penning traps. Our principle experiments are the Canadian Penning Trap experiment at Argonne National Lab- oratory, the TITAN Penning Trap experiment at TRIUMF and the Collinear Laser Spectroscopy Experiment at TRIUMF. The experiments determine moments, radii and masses of nuclei far from stability and provide data for nuclei of relevance in stellar processes and for the refinement of nuclear models, in general. Other areas of interest include the application of research methods to technical challenges (Applied Physics). Specifically: (1) RFQ-ion traps and lasers are used for the detection of low abundance species and for manipulating atoms on nanoscopic scales; (2) The creation of defects in avalanche photodiodes by single allows time-resolved studies of defect generation and annealing with ms resolution. We use laser techniques to study fundamental nuclear properties - radii, spins, and moments. The techniques are borrowed from atomic physics. In an atomic spectrum, a transition line splits into a number of components (the hyperfine structure), whose wavelengths depend on the size, shape, and spin of the nucleus. A lot of the really interesting phenomena (sudden changes of nuclear shape, for example) occur in exotic nuclei which lie far from nuclear stability. This means that our studies must be done on radioactive nuclei produced in reactions at particle accelerators. The challenge is therefore to find ways of studying very small samples (a few atoms, in some cases) of isotopes that may have lifetimes of only a few minutes, or seconds. At McGill, we are currently involved in the study of laser ion sources, through laser desorption and resonant ionization spectroscopic (RIS) techniques; selective injection of radioactive ions into an RFQ trap; and laser spectroscopic studies of radioactive ions. For this work, we use stable and CHEP - Centre for High Energy Physics Report 2007–2008 22 long-lived isotopes, and sometimes other rare species such as cluster ions. The applications of these methods in nuclear physics are carried out through extensive collab- orations at nuclear laboratories. Currently, we have an on-going laser spectroscopy program at ISOLDE (CERN), and a precise nuclear mass measurement project at TASCC (Chalk River). The possibility of initiating a new project at the recently funded high-intensity radioactive ion beam facility ISAC (TRIUMF) is being explored. In addition we are collaborating with the optoelectronic division of EG&G in the study of defects in avalanche photodiodes induced by fast collisions. Some of the resultant defects are bistable, causing the dark current to jump between two distinctly different levels. The results of this study will help us to understand the metastable nature of the defect configurations.

6.3 Ion Trap Techniques for mass Measurement and Laser Spectroscopy

Recently, a technique for ”catching” and storing ions from isotope separators in a radio frequency quadrupole trap has been developed by our group and is now being adapted for ion collection in a system designed to measure nuclear masses at CERN (Geneva). The same technique also appears to be very promising one for the capture and bunching of ion beams for use in laser spectroscopic measurements on nuclei. A new colinear spectroscopy beam line has been constructed at McGill as a pilot project to test this technique. Other interests are Electromagnetic Trapping and intertrap transfer, high-field confinement of charged particles, ion beam cooling, high accuracy nuclear mass measurements, high sensitivity detection of high mass biomolecules and the evolution of liquid surfaces under high electric fields (electrospray).

6.4 Theoretical Nuclear Energy Physics

Modern theoretical nuclear physics can be summarized as the study of strongly interacting many body systems. The 20th century is filled with many break-throughs in physics. One of such break- throughs was the discovery of accurate theory of strong interactions – quantum chromo-dynamics (QCD). This theory predicts that the quarks and which make up the nuclear matter can never exist as free particles in ordinary matter. However under extreme conditions such as one existed a few micro-second after the big-bang, a deconfinement phase transition will take place and quarks and glons can be freed to form a Quark-Gluon Plasma (QGP). The advent of high energy heavy ion colliders in Europe and North America caused a remarkable advance in this field. New and surprising experimental results and exciting new theoretical insights and predictions are continuously being published while large number of puzzles still remain to be investigated. In the study of heavy ion collision theory and in the energy range 30 MeV/ to many GeV/nucleon, the important questions to ask are:

Can we extract information about the nuclear equation of state? • Do we see a liquid-gas phase transition in the lower beam energy experiments? • What is the proper theoretical framework which can be used to describe intermediate energy • heavy ion collisions? CHEP - Centre for High Energy Physics Report 2007–2008 23

We pursue the theoretical study of strongly interacting matter under extreme conditions of temper- ature and density, such as that formed in relativistic nuclear collisions at terrestrial accelerators, and that in dense stellar objects. One of the reasons this topic is so appealing is that it involves aspects of nuclear, particle, condensed matter, and astrophysics. Put another way, we’re exploring the whole phase diagram of QCD, the theory of the strong interaction.

8 Seminars

The Centre sponsors five interleaving seminar series instrumental in the training of researchers:

A formal seminar series within the Centre attracts speakers from across Canada, the United • States and European visitors to North America. The seminars are an integral component of our activity and are of great value to all members of the Centre, especially to our students and postdoctoral researchers. They are also organized jointly with the Particle Physics group of the Universit´e de Montr´eal, so that further exchanges are generated.

A popular series is the weekly “pizza lunch” seminar, usually featuring a Centre theory • member discussing his or her current research in an informal atmosphere encouraging student participation.

Another series is the “Wednesday Meetings” seminar, where all members of our experimental • teams get together and discuss their research.

Our nuclear physics theory colleagues also maintain frequent seminars where guests from • outside are invited to present and share their research.

Finally, a few major workshops and large meetings are now being initiated by members of • our Centre on outstanding topics.

These seminars also provide a familiar setting in which graduate students and postdoctoral re- searchers gain valuable experience in presenting their work. All of our students, as well as most of our visitors give at least one of these talks sometime during their programme. Our permanent members are also contributing to the series. The list of seminars are available on the web under http://www.physics.mcgill.ca/chep/reports/chep 20072008 seminars.html

9 Publications (2007)

Publications, together with the training of our students and postdocs, are one of the most important elements of research, because they stimulate, guide, set goals to our undertakings and promote exchanges with other researchers. The Centre publications from the High Energy Physics database SPIRES are available on the web under http://www.physics.mcgill.ca/chep/reports/chep 20072008 publications.html

11 Summary and Outlook

The Centre for High Energy Physics (CHEP) is constantly growing in strength and stature over its wide field of research, covering numerous important aspects of the history of the universe and its puzzles. Thanks to the initiative of our members and a rich seminar program, numerous visitors come to us for talks and exchanges. Our members are also frequently invited outside to discuss their research progresses and present their results. On the experimental side, the start of the International ATLAS experiments has given a new and exciting impetus to our groups, with the McGill team well positioned nationally and internationally. Prospects for the International Collider or the Super-B projects to come considerably enrich our research program. Large numbers of research associates, postdocs, graduate and undergraduate students are con- stantly active in our centre. It is a measure of the liveliness and attraction of the groups that their numbers are slowly increasing over the years, with frequents renewals as most graduate or leave the group after their training for jobs and opportunities at other locations
