"LAr calorimeter commissioning and search for a light stop"
 Slideshow (PDF)
Extensive tests have been carried out with the ATLAS liquid argon( LAr) calorimeter system. This talk presents the highlights of the LAr commissioning activities. Supersymmetry searches at ATLAS are summarized, with a focus on the search for a light supersymmetric top squark (stop). A light stop is motivated by theories of electroweak baryogenesis in the Minimal Supersymmetric Standard Model (MSSM). An MSSM benchmark point, LST1, with a stop mass of 150 GeV is investigated for potential discovery with the ATLAS detector.
