| Abstract |    :  
                  This Letter presents a measurement of the W^{+}W^{-} production cross section in sqrt[s]=7 TeV pp collisions by the ATLAS experiment, using 34 pb^{-1} of integrated luminosity produced by the Large Hadron Collider at CERN. Selecting events with two isolated leptons, each either an electron or a muon, 8 candidate events are observed with an expected background of 1.7±0.6 events. The measured cross section is 41_{-16}^{+20}(stat)±5(syst)±1(lumi) pb, which is consistent with the standard model prediction of 44±3 pb calculated at next-to-leading order in QCD.  |
