Kurzfassung
A search for events with large missing transverse momentum, jets, and at least two taus has been performed using 2 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% CL visible cross section upper limit for new phenomena of 2.9 fb is set. For a minimal model of gauge-mediated supersymmetry breaking (GMSB), limits on the production cross section are set. A 95% CL lower limit of 32 TeV is set on the GMSB breaking scale Λ independent of tanβ. These limits provide the most stringent tests in a large part of the considered parameter space to date.
