Searches for R-partiy violating Supersymmetry in multileptonic final states — •Johannes Junggeburth, Zinonas Zinonos, and Hubert Kroha — Max-Planck-Institut für Physik

Supersymmetry is one of the most extensively tested theories in the physics programme of the Large Hadron Collider (LHC). If the discrete R-parity symmetry is conserved, the lightest supersymmetric particle (LSP) is stable, thus providing a dark-matter candidate. However, R-parity may be violated allowing the LSP to decay into Standard Model (SM) particles. Multileptonic final states provide an excellent signature to probe such supersymmetric scenarios due to the low SM background. In this talk, a search for events with at least four isolated charged leptons is presented which uses LHC proton-proton collision data collected by the ATLAS detector. The results are interpreted in terms of the visible cross-section for such new physics final states and in terms of various supersymmetric models with R-parity violation.
