Dark Matter, Cosmology and Accelerator Physics PROPOSAL Dark Matter, Cosmology and Accelerator Physics Dark matter is one the of cornerstones of modern cosmology, although it has not yet been directly detected, or produced in the laboratory. If dark matter is in the form of weakly- interacting massive particles, or WIMPs, then it will also represent a critical link between cosmology and the particle physics beyond the Standard Model. With a host of new dark matter experiments running and in various stages of preparation or R&D, the impending launch of new astrophysical probes, the anticipated turn-on of the Large Hadron Collider, and the planning of the International Linear Collider and Deep Underground Science and Engineering Lab, it is very timely to bring together members of these diverse communities to update the intellectual roadmap that connects these efforts. What SUSY models might be detectable at the LHC and/or ILC? How would models consistent with LHC/ILC data constrain what might exist in the cosmos? How do we define an optimal program for finding new signals at the LHC and ILC informed by the latest thinking of phenomenologists and the results of astrophysics. How would a detection of WIMPs in an elastic-scattering "direct detection" experiment constrain particle physics? What consistency checks would we be able to perform to correlate constraints or detections across these diverse techniques to pin down the parameters of SUSY, or to know with confidence that particles in the lab are the same as those in the sky? How would we determine if the new particles produced in accelerators occur at the dark matter density, ie, are truly the dark matter indicated by WMAP, and inferred by observations of Galactic Clusters? Looking further ahead, how will what is seen in the coming few years inform the design of the International Linear Collider? Several shorter workshops aimed at these questions have or will soon take place (For example: UW's INT, Aug 2005; Santa Monica, Feb 2006; and SUSY06, Irvine, June 2006). At Aspen, we propose to bring together an international group of theorists and experimentalists from the dark matter search community and the accelerator-based particle physics community to consider these questions. The goal of the workshop will be to produce a Dark Matter Resource Book, which presents the current understanding of the field and provides guidance on what we may learn in the future as new evidence emerges. Participants: We have recently contacted to the following list of physicists, and more than half have expressed strong interest in attending the workshop (indicated with a *): Jim Alexander*, Elena Aprile*, Howard Baer*, Ted Baltz*, Marco Battaglia, Laura Baudis, Genevieve Belanger*, Pierluigi Belli, Elliot Bloom*, Wim de Boer, Fawzi Boudjema, Blas Cabrera*, Marcela Carena*, Richard Cavanaugh*, David Cerdeno*, Juan Collar*, Joakim Edsjo*, John Ellis*, Jonathan Feng*, Katie Freese*, Richard Gaitskell*, Christiano Galbiati, Graciela Gelmini, Fabiola Gianotti, Francis Halzen*, Sven Heinemeyer*, Dan Hooper*, Per Olof Hulth*, Marc Kamionkowski*, Gordon Kane*, Peter Michelson*, Nojiri Mihoko, Filip Moortgat, Harry Nelson, Jeff Martoff, Konstantin Matchev, Keith Olive, Luc Pape, Michael Peskin*, Tilman Plehn, Giacomo Polesello, Stuart Raby, Steve Ritz*, Albert De Roeck*, Leszek Roszkowski*, Carlo Rubbia, Bernard Sadoulet*, Geraldine Servant*, Stefan Shael*, Tom Shutt, Nigel Smith, Neil Spooner, Glenn Starkman*, Leo Stodolsky, Greg Tarle*, Masahiro Teshima, Dan Tovey, Daniel Treille, Mani Tripathi, Mike Turner, Martin J.

  • Judicial Review of Uncertain Risks in Scientific Research
    Chapter 6 Judicial Review of Uncertain Risks in Scientific Research Eric E. Johnson Abstract It is difficult to neutrally evaluate the risks posed by large-scale leading- edge science experiments. Traditional risk assessment is problematic in this context for multiple reasons. Also, such experiments can be insulated from challenge by manipulating how questions of risk are framed. Yet courts can and must evaluate these risks. In this chapter, I suggest modes of qualitative reasoning to facilitate such evaluation. Keywords Risk · Risk scenarios · Law · Courts · Science · Scientific research · Particle physics · Black holes · LHC 6.1 Introduction In the world of engineering, uncertainty is anathema. Whether designing a nuclear power plant or planning a system of levees, engineers do not like surprises. Exper- imental scientific research, however, thrives on uncertainty. Reaching beyond the current state of knowledge is the whole point of the enterprise. Whether probing the planets or trying to create new particles, scientists would love to see a surprise around every corner. Uncertainty goes hand in hand with aspirations to explore and discover. This special role for uncertainty in scientific research makes questions of catastrophic risk from science experiments particularly interesting. What is more, 1See Hawai‘i County Green Party v.

In this paper, we conduct an extensive study of hidden sector dark matter, covering a wide range of dark matter spins, mediator spins, interaction diagrams, and annihilation final states, in each case determining whether the annihilations are s-wave (thus enabling efficient annihilation in the universe today). We then go on to consider a variety of portal interactions that allow the hidden sector annihilation products to decay into the Standard Model. We broadly classify constraints from relic density requirements and dwarf spheroidal galaxy observations. In the scenario that the hidden sector was in equilibrium with the Standard Model in the early universe, we place a lower bound on the portal coupling, as well as on the dark matter’s elastic scattering cross section with nuclei.

  • W-Boson and Trident Production in Tev--Pev Neutrino Observatories
    W -boson and trident production in TeV{PeV neutrino observatories Bei Zhou1, 2, ∗ and John F. Beacom1, 2, 3, y 1Center for Cosmology and AstroParticle Physics (CCAPP), Ohio State University, Columbus, OH 43210 2Department of Physics, Ohio State University, Columbus, OH 43210 3Department of Astronomy, Ohio State University, Columbus, OH 43210 (Dated: February 18, 2020) Detecting TeV{PeV cosmic neutrinos provides crucial tests of neutrino physics and astrophysics. The statistics of IceCube and the larger proposed IceCube-Gen2 demand calculations of neutrino- nucleus interactions subdominant to deep-inelastic scattering, which is mediated by weak-boson couplings to nuclei. The largest such interactions are W -boson and trident production, which are mediated instead through photon couplings to nuclei. In a companion paper [1], we make the most comprehensive and precise calculations of those interactions at high energies. In this paper, we study their phenomenological consequences. We find that: (1) These interactions are dominated by the production of on-shell W -bosons, which carry most of the neutrino energy, (2) The cross section on water/iron can be as large as 7.5%/14% that of charged-current deep-inelastic scattering, much larger than the quoted uncertainty on the latter, (3) Attenuation in Earth is increased by as much as 15%, (4) W -boson production on nuclei exceeds that through the Glashow resonance on electrons by a factor of ' 20 for the best-fit IceCube spectrum, (5) The primary signals are showers that will significantly affect the detection rate in IceCube-Gen2; a small fraction of events give unique signatures that may be detected sooner.

    SLAC-PUB-3101 April 1983 (T/E) SEARCH FOR SUPERSYMMETRY IN TOPONIUM DECAYS* JOHN ELLIS Stanjord Linear Accelerator Center Stanford Uniueraity, Stanford, California 9@05 and SERGERUDAZ School of Physics and Astronomy University of Minnesota, Minneapolis, Minnesota 55455 ABSTRACT Although cosmology and unification suggest that the mass of the gluino is larger than about 14 GeV, in many theories of broken supersymmetry the photino 5, gluino S and one of the spin-zero partners i of the t quark can be lighter than mt. We calculate Z-T- the decay rates for toponium + 5 S, r 5 and t t and show that in many models they can be as large as, or larger than, the rate for toponium ---, e+e- decay. If it is kinematically accessible, the decay t --* t+q dominates the decays of toponium as well as those of naked top states. Submitted to Physics Letters B * Work supported by the Department of Energy, contracts DEAC03-76SF00515 and DEAC02-83ER40051. One obstacle to the experimental search [l] for supersymmetry (susy) is our the- oretical ignorance about the likely masses of supersymmetric particles. This means that we cannot be sure where susy will first appear, and must plan a broad-band search. The production and detection of supersymmetric particles in hadron-hadron collisions (21, lepton-hadron collisions [3,4] and e+e- annihilation [3,5,6] have been extensively discussed. In the case of e+e- annihilation, there have been discussions of the production of squarks and gluinos in the continuum and of gluinos in heavy quarkonium decays [3,5,6].

The origin of the most energetic particles in the universe could be related to extremely energetic astronomical phenomena or other exotic processes, such as the decay of the super-heavy dark matter in the halo of our galaxy or topological defects created in an early phase of the development of the universe. In order to clarify their origin, it is essential to develop next-generation techniques for detection of their particles by large amounts of statistics. The workshop will address the road map and near-future prospects of cosmic rays and neutrinos above the PeV scale. Included topics are reviews of the latest results, upcoming detectors and techniques, and related theory topics. The anticipated structure is a series of presentations with ample time for discussion and working sessions.

  • Constraining Sterile Neutrino Interpretations of the LSND and Miniboone Anomalies with Coherent Neutrino Scattering Experiments

Coherent scattering is universal across all active neutrino flavors, and thus can provide a measurement of the total Standard Model neutrino flux. By performing measurements over different baselines and making use of timing information, it is possible to significantly reduce the systematic uncertainties and to independently measure the fluxes of neutrinos that originate as νμ or as either νe or ν¯μ. We find that a 100 kg CsI detector would be sensitive to a large fraction of the sterile neutrino parameter space that could potentially account for the LSND and MiniBooNE anomalies.
