Expected Performance of the ATLAS Detector in GMSB Models with Tau Final\n States

Le résumé fourni par la source

Gauge Mediated Supersymmetry Breaking (GMSB) models provide a possible\nmechanism to mediate Supersymmetry to the visible sector. In these models the\nlightest supersymmetric particle (LSP) is usually the gravitino, while the\nnext-to-lightest supersymmetric particle (NLSP) is either a neutralino or a\nslepton. In the case of a stau NLSP events with large missing transverse\nenergy, highly energetic jets and up to four $\\tau$ leptons are expected in\n$pp$-collisions at the LHC. A study of the expected performance of the ATLAS\ndetector in GMSB scenarios with a stau NLSP for a LHC center-of-mass energy of\n$\\sqrt{s}$ = 10 TeV is presented. A cut-based selection has been optimised\nusing a typical GMSB scenario and a scan of the GMSB parameter space has been\nperformed to determine the discovery reach as a function of the integrated\nluminosity. In addition, the invariant mass distribution of two $\\tau$ leptons\nhas been used to study the measurement of masses of supersymmetric particles\nwith larger event samples.\n
