Abstract

In SUSY models with Gauge Mediated Supersymmetry Breaking (GMSB) a gravitino is the lightest SUSY particle (LSP), while a neutralino or a slepton is the next-to-lightest (NLSP). For the pair-production of SUSY particles at the LHC large missing transverse energy (from the gravitinos) and two photons or leptons in the final state are expected, if the NLSP decays inside the detector. In the case of stable NLSPs, interesting signatures consist of non-pointing photons or heavy stable charged particles. In this presentation methods developed by the ATLAS and CMS collaborations and the expected performance derived from simulations are summarized.
