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 pro...

description 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. In this talk, it is shown how such non-pointing photons can be reconstructed and identified along with methods to estimate Standard Model backgrounds. Furthermore, techniques are shown which demonstrate how the lifetime of the neutralino could be measured.
