Abstract

A search for production of supersymmetric particles in final states containing jets, missing transverse momentum, and at least one hadronically decaying τ lepton is presented. The data were recorded by the ATLAS experiment in $\sqrt{s} = 7 TeV$ 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 $M_{mess} = 250 TeV$ , $N_{5} = 3$ , $μ > 0$ , and $C_{grav} = 1$ . The production of supersymmetric particles is excluded at 95% C.L. up to a supersymmetry breaking scale $Λ = 30 TeV$ , independent of tan β, and up to $Λ = 43 TeV$ for large tan β.
