Phenomenology of Gluino Searches at the Tevatron

Abstract

Present data indicates that the gluino (if it exists) must be heavier than about 95~GeV. During the next few years as the Tevatron integrated luminosity increases, gluino searches will be able to probe the mass range between 100 and 200~GeV. For masses in this range, a variety of gluino decay modes can provide viable signatures for gluino detection. Apart from the classic missing transverse energy signal, the detection of high transverse momentum like-sign dileptons may be the cleanest signature for gluino production. Other signatures such as the production of a hard photon in the gluino cascade decay may also play an important role in confirming the supersymmetric origin of events originating from gluino production and decay.
