Search for Long-Lived Particles out-of-time with LHC Collisions in ATLAS

R-hadrons are massive, long-lived particles predicted in several Supersymmetry~scenarios. Studies exploring the discovery potential of R-hadrons~at the ATLAS detector have mainly focused on gluino R-hadrons. ~This talk describes a search for gluinos which have come to rest within the detector~volume, particularly the calorimeter, and decay at some later time.~ We search for jets produced from the 2- or 3- body decays of the gluinos that have stopped within the calorimeter. ~The search is conducted in empty bunch crossings to greatly reduce backgrounds from pp collisions.~ Simple selection criteria enable the discrimination of signal events from the main background, which comes from cosmic rays.
