An inclusive search for anomalous production of two prompt, isolated muonswith the same electric charge is presented. The search is performed in a datasample corresponding to 1.6 fb^-1 of integrated luminosity collected in 2011 atsqrt(s) = 7 TeV with the ATLAS detector at the LHC. Muon pairs are selected byrequiring two isolated muons of the same electric charge with pT > 20 GeV andabs(eta) < 2.5. Minimal requirements are placed on the rest of the eventactivity. The distribution of the invariant mass of the muon pair m(mumu) isfound to agree well with the background expectation. Upper limits on the crosssection for anomalous production of two muons with the same electric charge areplaced as a function of m(mumu) within a fiducial region defined by the eventselection. The fiducial cross- section limit constrains the like-sign top-quarkpair-production cross section to be below 3.7 pb at 95% confidence level. Thedata are also analyzed to search for a narrow like-sign dimuon resonance aspredicted for e.g. doubly charged Higgs bosons (H++/H--). Assuming pairproduction of H++/H-- bosons and a branching ratio to muons of 100% (33%), thisanalysis excludes masses below 355 (244) GeV and 251 (209) GeV for H++/H--bosons coupling to left-handed and right-handed fermions, respectively.
