Interpretation of same-sign dilepton events at ATLAS with a simplified SUSY model

A search for supersymmetric particles was performed in events with two like-sign leptons using 35 pb^-1 of integrated luminosity recorded by the ATLAS detector in pp collisions at sqrt(s)=7 TeV. No excess above the Standard Model prediction is observed. The results are expressed in terms of a simplified model which contains the minimal particle content and is parametrized directly in terms of the sparticle masses. Upper limits on the production cross section times branching ratios are calculated for three specific decay modes which would produce like-sign dilepton events, and presented as a function of the sparticle masses.
