Physics

Scientific paper

We present a search for anomalous production of two prompt like-sign leptons and constraints on physics beyond the Standard Model. The search is performed using a data sample corresponding to an integrated luminosity of 5 fb-1, collected in 2011 at √s = 7 TeV by the ATLAS detector at the LHC. Lepton pairs are selected inclusively by requiring two isolated leptons of the same electric charge with pT> 20 GeV. The invariant mass distribution is examined and limits are placed on the anomalous production cross section as function of invariant mass with respect to a fiducial region close to that of the experimental selection. The inclusive search is also interpreted within a few different models of physics beyond the Standard Model.
