Sumario:The reconstruction of non pointing photons is a key feature for studying Gauge Mediated Supersymmetry Breaking (GMSB) models at the LHC. In this note the photon angular resolution of the ATLAS electromagnetic calorimeter is characterized from a detailed simulation of the detector. Resulting performance are used to reconstruct GMSB events with a fast simulation program, taking into account reconstruction effects. Finally, the sensitivity in extracting the sparticles masses and the lightest neutralino lifetime is estimated.
