Search for supersymmetry with jets, missing transverse momentum and at least one hadronically decaying t lepton in proton–proton collisions at vs = 7 TeV with the ATLAS detector
A search for production of supersymmetric particles in final states containing jets, missing transverse momentum, and at least one hadronically decaying t lepton is presented. The data were recorded by the ATLAS experiment in v s = 7 TeV proton–proton collisions at the Large Hadron Collider. No excess above the Standard Model background expectation was observed in 2.05 fb-1 of data. The results are interpreted in the context of gauge mediated supersymmetry breaking models with Mmess = 250 TeV, N5 = 3, µ > 0, and Cgrav = 1. The production of supersymmetric particles is excluded at 95% C.L. up to a supersymmetry breaking scale ? = 30 TeV, independent of tanß, and up to ? = 43 TeV for large tanß.
