ATLAS Physics Group

atlas_logoATLAS is one of the four large detectors at the proton-proton collider LHC (Large Hadron Collider) at the Centre of European Particle Physics CERN (Conseil Européen pour la Recherche Nucléaire). The initial LHC run in the years 2010-2012 brought a variety of new physics results, culminating in the observation of the Higgs boson in 2012. The LHC has begun to touch an energy regime probed never before in an accelerator. Among the main physics goals of ATLAS are the investigation of the Higgs boson, the search for Supersymmetry and other new phenomena beyond the standard model of particle physics (e.g. large extra dimensions), physics of the top quark, of B hadrons and of weak gauge bosons, as well as tests of Quantum Chromodynamics (QCD) at high energies.

Our group is active in many of these areas, analyzing the reactions that occur at the LHC and improving reconstruction and analysis methods to match the rapid increase in size of the available data set. We also share responsibility for operating and monitoring the data quality in particular of the ATLAS Pixel Detector, which operates at a distance of only 5cm to the interaction point, as well as future upgrades of this detector, such as a new innermost layer of the pixel detector at 3.5cm which was installed in 2014.
