Abstract:

This Letter reports a measurement of the WW production cross section in 鈭歴=7 TeV pp collisions using data corresponding to an integrated luminosity of 1.02 fb-1 collected with the ATLAS detector. Using leptonic decays of oppositely charged W bosons, the total measured cross section is 蟽(pp鈫扺W)=54.4卤4.0(stat.)卤3.9(syst.)卤2.0(lumi.) pb, consistent with the Standard Model prediction of 蟽(pp鈫扺W)=44.4卤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. 漏 2012 CERN.
