The ATLAS experiment ATLAS is the largest of the experiments at the Large Hadron Collider. Steven Goldfarb is a particle physicist from the University of Melbourne working on the ATLAS Experiment at CERN. The research programme at CERN covers topics from kaons to cosmic rays, and from the Standard Model to supersymmetry, Steering and focusing: magnets and superconductivity, From a cavern 100 metres below a small Swiss village, the 7000-tonne ATLAS detector is probing for fundamental particles. He has served as Muon Software Coordinator, Outreach Coordinator, and contributed to early studies in the search for the Higgs boson. CERN Computer Centre (Image: Veronika McQuade/CERN) Collisions among proton bunches occur inside the ATLAS experiment at CERN’s Large Hadron Collider up to 40 million times a second. To explore this exciting possibility, the ATLAS experiment is pursuing an ambitious program of direct searches for new hypothetical particles with novel couplings, as well as exploiting abundant SM processes to probe exceedingly rare flavour violating decays.

The ATLAS experiment detects and measures proton-proton collisions at the Large Hadron Collider (LHC). Welcome to ATLAScraft, a map of CERN and the ATLAS detector created in the popular game Minecraft! At 46 m long, 25 m high and 25 m wide, the 7000-tonne ATLAS detector is the largest volume particle detector ever constructed. This article on the ATLAS experiment at CERN is a guest article by Anja Sjöström, an IB diploma student from Switzerland.. The Michigan State University (MSU) ATLAS Group is involved in a number of searches for new phenomena Beyond the Standard Model (BSM) of particle physics, as well as precision measurements of the Standard Model (SM). - Located at the heart of the experiment, the ATLAS Inner Detector can measure the position of charged particles that pass through it to better than a 100th of a millimetre! Coordinates ATLAS (A Toroidal LHC ApparatuS) is the largest, general-purpose particle detector experiment at the Large Hadron Collider (LHC), a particle accelerator at CERN (the European Organization for Nuclear Research) in Switzerland The experiment is designed to take advantage of the unprecedented energy available at the LHC and observe phenomena that involve highly massive … In addition, a milestone analysis on the search for flavour-violating Z-boson decays into a -lepton and a light lepton (electron or muon), which has for the first time exceeded the LEP sensitivity, will be discussed. Among them, several searches for scalar leptoquark pair production, where both flavour-diagonal and cross-generational couplings are being tested, will be presented. To explore this exciting possibility, the ATLAS experiment is pursuing an ambitious program of direct searches for new hypothetical particles with novel couplings, as well as exploiting abundant SM processes to probe exceedingly rare flavour violating decays. ATLAS is one of the four major experiments at the Large Hadron Collider (LHC) at CERN. Among them, several searches for scalar leptoquark pair production, where both flavour-diagonal and cross-generational couplings are being tested, will be presented. PLOT: ATLAS Experiment © 2015 CERN On 17 March, ATLAS presented their latest Higgs physics results at an LHC seminar at CERN from data collected during the LHC's first run. At 46 m long, 25 m high and 25 m wide, the 7000-tonne ATLAS detector is the largest volume particle detector ever constructed. The first ATLAS inner detector end-cap after complete insertion within the Liquid Argon Cryostat. The LHC Experiments Committee and CERN Director-General, Chris Llewellyn Smith, approve the construction of the ATLAS detector. It sits in a cavern 100 m below ground near the main CERN site, close to the village of Meyrin in Switzerland. This talk will present recent ATLAS results based on the full Run 2 dataset that are part of this program. A brief overview of the expected performance of the detector when the Large Hadron Collider begins operation is also presented. ". Designed to fi nd out why the Universe is like it is today, ATLAS will probe more deeply into matter than ever before and explore new The Physics ATLAS explores a range of physics topics, with the primary focus of improving our understanding of the fundamental constituents of matter. Last year, the ATLAS experiment at CERN’s LHC observed two photons, particles of light, ricocheting off one another and producing two new photons. Collaborators from the ATLAS experiment, the largest particle detector in the world, are seen in CERN's new building 40. 12:00. The ATLAS Experiment at CERN is searching for signs of supersymmetry, a theory which extends the Standard Model to answer many unsolved questions about the Universe. As the first Technical Design Reports are approved, ATLAS teams all over the world begin building detector components and worked on final technical developments. This talk will present recent ATLAS results based on the full Run 2 dataset that are part of this program. It sits in a cavern 100 m below ground near the main CERN site, close to the village of Meyrin in Switzerland. Today ATLAS and other particle physics experiments at CERN's Large Hadron Collider (LHC) began recording physics data from 13 TeV proton collisions, which allow for precision studies of the Higgs boson and other Standard Model particles, as well as the search for new particles with higher masses. The Standard Modeldescribes the elementary subatomic particles of the universe which have been experimentally seen. On July 4, 2012, it was announced that the long sought after Higgs boson particle was believed to have been found by the ATLAS and CMS experiments associated with the Large Hadron Collider at CERN.Boston University personnel have been heavily involved in the ATLAS experiment.

As hinted by anomalies currently seen in the B-meson sector, new physics might exhibit a different flavour structure than the Standard Model. More than 3000 scientists from 174 institutes in 38 countries work on the ATLAS experiment (February 2012).

Beams of particles from the LHC collide at the centre of the ATLAS detector making collision debris in the form of new particles, which fly out from the collision point in all directions.

The International School for Advanced Studies (SISSA) was founded in 1978 and was the first institution in Italy to promote post-graduate courses leading to a Doctor Philosophiae Six different detecting subsystems arranged in layers around the collision point record the paths, momentum, and energy of the particles, allowing them to be individually identified. The interactions in the ATLAS detectors create an enormous flow of data. The instrumentation housed inside the inner end-cap must be kept cool to avoid thermal noise. The ATLAS detector as installed in its experimental cavern at point 1 at CERN is described in this paper. A huge magnet system bends the paths of charged particles so that their momenta can be measured. The ATLAScraft project is organised by researchers at the University of Oxford and the University of Birmingham, who guided a team of students from several schools in the United Kingdom in recreating parts of the ATLAS detector in Minecraft. The combination is based on the analyses of the Higgs boson decay modes H→γγ, ZZ*, WW*, ττ, bb¯, μμ, searches for decays into invisible final states, and on measurements of off-shell Higgs boson production. We do so using the world's largest and most complex scientific instruments. Complex data-acquisition and computing systems are then used to analyse the collision events recorded. To reach that precision, the detector must be aligned to equal or better accuracy. Steven Goldfarb, Physicist, University of Melbourne, ATLAS Experiment. What are the basic building blocks of matter?
