Micro Cosmª DESY Explores What Binds the Universe Together at Its Core MICRO COSMª DESY explores what binds the universe together at its core On the trail of quarks, supersymmetry and extra dimensions – particle physicists at DESY inquire into the very structure of our world. Using large accelerator facilities, supercomputers and leading-edge technology at the limits of the possible, they shed light on the secrets of the universe’s fundamental forces and building blocks. In pursuit of these goals, they work in national and international networks with colleagues from all over the world. Accelerators | Photon Science | Particle Physics Deutsches Elektronen-Synchrotron A Research Centre of the Helmholtz Association In the heart of the H1 detector at the HERA accelerator ª CONTENTSª DESY Insight starts here 4 DESY is one of the world’s leading accelerator centres for investigating the structure of matter. DESY develops, builds and uses particle accelerators and detectors for photon science and particle physics. TIME Insight into the world of elementary particles 6 TRAVEL Particle physics explores questions that are central to our understanding of the universe: What are we made of? What are the building blocks of our world and what holds them together? How did the universe come into existence and how did it become what it is today? ... WORLD The big mysteries of the universe 8 VIEW In the course of the last century, physicists ventured into ever smaller dimensions. Today, the Standard Model of particle physics very successfully describes the fundamental building blocks of our world and the forces acting between them. Nevertheless, central questions remain unanswered. ... WORLD DESY: An international centre for particle physics 10 RESEARCH All over the world, scientists strive to answer the key questions of the origin and nature of our universe. However, it will only be possible to make headway here if everyone involved joins together in national and international research networks. This networking – across political and cultural borders – enjoys a long tradition at the particle physics research centre DESY. POINTING HERA: The super electron microscope 12 THE WAY The Hadron-Electron Ring Accelerator HERA was the largest particle accelerator at DESY and Germany’s largest research instrument. For 15 years, this gigantic super electron microscope provided physicists with the world’s sharpest view of the proton’s interior. ... WORLD LHC: The most powerful accelerator in the world 20 MACHINE In 2008, the world’s largest machine went into operation at the European research centre CERN near Geneva: the Large Hadron Collider LHC, a gigantic particle accelerator ring with a circumference of 26.7 kilometres. At a depth of up to 175 metres below Geneva’s outskirts and the French Jura mountains, protons or heavy ions collide with one another head-on – at the highest energies ever attained in a particle accelerator. ... UNCHARTED ILC: The project for the future of particle physics 30 TERRITORY Whereas the proton accelerator LHC will fling open the door to the terascale for the first time and offer exciting initial insights into this uncharted territory, physicists will only be able to solve the big mysteries of the universe in combination with a second, precision machine – a linear accelerator in which electrons and their antiparticles, positrons, collide at the highest energies. ... LIGHT ALPS: Searching for lightweight particles 38 WEIGHT Researchers at DESY are interested not only in extremely heavy particles, which have to be generated by means of large high-energy accelerators; very light particles at the lower end of the energy scale can also point the way toward unknown physics phenomena. ... SPACE IceCube and CTA: Windows on the universe 40 MESSENGERS The DESY scientists also conduct research in astroparticle physics, a research field that combines methods and questions from astrophysics, cosmology and particle physics. Various kinds of particle from the cosmos constantly reach the Earth – particles that can provide insights into events happening in the depths of the universe. ... THOUGHT Theory: The hunt for the Theory of Everything 46 FACTORY Theoretical particle physics strives to piece together the big picture that underlies the host of experimental findings. Without such theory, the best experiment would be worthless. ... DESYª Insight starts here DESY is one of the world’s leading accelerator centres for investigating the structure of matter. DESY develops, builds and uses particle accelerators and detectors for photon science and particle physics. DESY carries out fundamental research in a range of scientific fields and focuses on three principal areas: º Accelerators: DESY develops, builds and operates large facilities that accelerate particles to extremely high energies. º Photon science: Physicists, chemists, geologists, biologists, medical researchers and material scientists use the special light from DESY’s accelerators to study structures and processes in the microcosm. º Particle physics: Scientists from around the world use accelerators to investigate the fundamental building blocks and forces of the universe. The spectrum of research at DESY is correspondingly diverse – as is the cooperation with partners both national and international. All in all, more than 3000 scientists from 45 countries come to Hamburg each year to work at DESY.

  • CERN Courier Sep/Oct 2019
    CERNSeptember/October 2019 cerncourier.com COURIERReporting on international high-energy physics WELCOME CERN Courier – digital edition Welcome to the digital edition of the September/October 2019 issue of CERN Courier. During the final decade of the 20th century, the Large Electron Positron collider (LEP) took a scalpel to the subatomic world. Its four experiments – ALEPH, DELPHI, L3 and OPAL – turned high-energy particle physics into a precision science, firmly establishing the existence of electroweak radiative corrections and constraining key Standard Model parameters. One of LEP’s most important legacies is more mundane: the 26.7 km-circumference tunnel that it bequeathed to the LHC. Today at CERN, 30 years after LEP’s first results, heavy machinery is once again carving out rock in the name of fundamental research. This month’s cover image captures major civil-engineering works that have been taking place at points 1 and 5 (ATLAS and CMS) of the LHC for the past year to create the additional tunnels, shafts and service halls required for the high-luminosity LHC. Particle physics doesn’t need new tunnels very often, and proposals for a 100 km circular collider to follow the LHC have attracted the interest of civil engineers around the world. The geological, environmental and civil-engineering studies undertaken during the past five years as part of CERN’s Future Circular Collider study, in addition to similar studies for a possible Compact Linear Collider up to 50 km long, demonstrate the state of the art in tunnel design and construction methods. Also in this issue: a record field for an advanced niobium-tin accelerator dipole magnet; tensions in the Hubble constant; reports on EPS-HEP and other conferences; the ProtonMail success story; strengthening theoretical physics in DIGGING southeastern Europe; and much more.

  • Measurement of the W → Eν Cross Section with Early Data from the CMS Experiment at CERN
    Imperial College London Blackett Laboratory High Energy Physics Measurement of the W eν cross section ! with early data from the CMS experiment at CERN Nikolaos Rompotis A thesis submitted to Imperial College London for the degree of Doctor of Philosophy and the Diploma of Imperial College. January 2011 Abstract The Compact Muon Solenoid (CMS) is a general purpose detector designed to study proton-proton collisions, and heavy ion collisions, delivered by the Large Hadron Col- lider (LHC) at the European Laboratory for High Energy Physics (CERN). This thesis describes a measurement of the inclusive W eν cross section at 7 TeV centre of mass ! energy with 2:88 0:32 pb−1 of LHC collision data recorded by CMS between March ± and September 2010. W boson decays are identified by the presence of a high-pT electron that satisfies selec- tion criteria in order to reject electron candidates due to background processes. Electron selection variables are studied with collision data and found to be in agreement with expectations from simulation. A fast iterative technique is developed to tune electron selections based on these variables. Electron efficiency is determined from simulation and it is corrected from data using an electron sample from Z decays. The number of W candidates is corrected for remaining background events using a fit to the missing transverse energy distribution. The measured value for the inclusive W production cross section times the branching ratio of the W decay in the electron channel is: σ(pp W +X) BR(W eν) = 10:04 0:10(stat) 0:52(syst) 1:10(luminosity) nb; ! × ! ± ± ± which is in excellent agreement with theoretical expectations.

  • Representing UKESM at CERN
    Representing UKESM at CERN Lee de Mora, Plymouth Marine Laboratory (PML) and UKESM core group Before I started working in the UKESM project, I worked on an entirely different project: the ATLAS experiment at CERN. CERN is the European Organization for Nuclear Research: it is the largest particle physics laboratory in the world and hosts the Large Hadron Collider, as well as many significant physics experiments. Between 2006 and 2010, I completed a PhD working on B-physics with the ATLAS detector, including two years at the CERN site just outside Geneva. I was quite lucky to be on site for the excitement of the first beam, the first collisions and the early results. Perhaps because of the contrast between my PhD and my current work with the UKESM, the CERN alumni network invited me to participate in a panel discussion at their annual careers event this November. The target audience for this event was current PhD students and early career scientists at CERN, who for whatever reason want to leave the field of particle physics or who are unable to remain. The goal of the event was to put them in contact with CERN alumni in other fields and to demonstrate that life is indeed possible for physicists outside the world of high energy physics. The panel discussion was led by Sebastian Bott of the alumni network, and consisted of Sarah Livermore, from the UK committee for climate change; Xavier Rouby, a consultancy entrepreneur; Jacopo Nardulli, an international baccalaureate science teacher; and myself, representing the UK’s earth system modelling project.

Cosmic collisions As the LHC experiments are again collecting data for physics, we touch base on the challenges that high-energy collisions and very intense beams represent for computing. The challenge extends far beyond the lifetime of the LHC if we look at data preservation, which must define winning strategies and permanent solutions to the problem. This month, we also feature CERN’s unique kaon factory and CMS’s powerful algorithm, which aims to identify and reconstruct individually all of the particles produced in a collision. The cover goes to AugerPrime in the Argentinian Pampas: the challenges that lie ahead here will involve a large community of scientists and innovative hardware solutions. News from CERN, BEPCII and HESS (the latter in Astrowatch) also features in the June issue. Last but not least, after a short but intense “intermezzo”, Antonella Del Rosso steps down and leaves the floor to the new editor, Matthew Chalmers.
