Search for supersymmetry with jets, missing transverse momentum, tau leptons and one light lepton at the ATLAS detector — Philip Bechtle, Klaus Desch, Till Nattermann, Oliver Ricken, Steffen Schaepe, and •Martin Schultens — University of Bonn

One of the major goals in the physics program of the ATLAS experiment at the Large Hadron Collider (LHC) is the search for supersymmetric extensions of the Standard Model of particle physics (SUSY). In some SUSY models, tau leptons can be a very important signature.

The tau lepton either decays into hadrons or into a lighter lepton (electron or muon). Due to the big background contributions at the LHC, pure hadronic final states are difficult to analyze. The final state with one leptonically decaying tau however, provides the opportunity for good background suppression and has promising discovery potential as well.

In this presentation recent results in the search for final states with tau leptons and one light lepton (electron or muon) will be presented. These results are interpreted in a SUSY scenario with gauge-mediated SUSY breaking (GMSB).
