  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
sqrt(s) = 7 TeV with the ATLAS detector at the LHC. Pairs of leptons (ee, emu,
and mumu) with large transverse momentum are selected, and the dilepton
invariant mass distribution is examined for any deviation from the Standard
Model expectation. No excess is found, and upper limits on the production cross
section of like-sign lepton pairs from physics processes beyond the Standard
Model are placed as a function of the dilepton invariant mass within a fiducial
region close to the experimental selection criteria. The 95% confidence level
upper limits on the cross section of anomalous ee, emu, or mumu production
range between 1.7 fb and 64 fb depending on the dilepton mass and flavour
combination.
