Search for anomalous production of prompt like-sign lepton pairs at √s =7 TeV with the ATLAS detector

An inclusive search for anomalous production of two prompt, isolated leptons with the same electric charge is presented. The search is performed in a data sample corresponding to 4.7 fb -1 of integrated luminosity collected in 2011 at √s =7 TeV with the ATLAS detector at the LHC. Pairs of leptons (e...
