Signatures of GMSB with Non-Pointing Photons at the ATLAS Detector

Signatures of gauge-mediated supersymmetry breaking include events in which the NLSP is a neutralino decaying to a photon and a gravitino. In this scenario, the photon can have a distinct signature of apparently late arrival in the calorimeter and a directionality not consistent with having been produced at the primary interaction point. These 'non-pointing' photons can be reconstructed and identified. Furthermore, techniques are shown which demonstrate how the lifetime of the neutralino could be measured.
