Abstract
This Letter reports a measurement of the WW production cross section in√s = 7 TeV pp collisions using data corresponding to an integrated luminosity of 1.02 fb[superscript −1] collected with the ATLAS detector. Using leptonic decays of oppositely charged W bosons, the total measured cross section is σ(pp→WW) = 54.4±4.0 (stat.) ±3.9 (syst.) ±2.0 (lumi.) pb, consistent with the Standard Model prediction of σ(pp→WW) = 44.4±2.8 pb. Limits on anomalous electroweak triple-gauge couplings are extracted from a fit to the transverse-momentum distribution of the leading charged lepton in the event.
