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.
