GMSB SUSY models with non pointing photons signatures in ATLAS at the LHC

Abstract

The reconstruction of non pointing photons is a key feature for studying gauge mediated supersymmetry breaking (GMSB) models at the LHC. In this article the angular resolution of the ATLAS electromagnetic calorimeter is characterized from a detailed simulation of the detector. Resulting performances are used to reconstruct GMSB events with a fast simulation program, taking into account reconstruction effects. Finally, the sensitivity to extract the sparticles masses and the lightest neutralino lifetime is estimated.
