Search for supersymmetry in events with large missing transverse momentum, jets, and at least one tau lepton in 7 TeV proton-proton collision data with the ATLAS detector

A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, and at least one hadronically decaying ?????? lepton, with zero or one additional light lepton (e/??????), has been performed using 4. 7 fb-1 of proton-proton collision data at ?????????s=7 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectation is observed and a 95 % confidence level visible cross-section upper limit for new phenomena is set. In the framework of gauge-mediated SUSY-breaking models, lower limits on the mass scale ?????? are set at 54 TeV in the regions where the ??????1 is the next-to-lightest SUSY particle (tan??????>20). These limits provide the most stringent tests to date of GMSB models in a large part of the parameter space considered. ?????? 2012 CERN for the benefit of the ATLAS collaboration.
