Title: Measurement of the W W cross section in root s=7 TeV pp collisions with the ATLAS detector and limits on anomalous gauge couplings

Abstract

This Letter reports a measurement of the WW production cross section in {radical}s = 7 TeV pp collisions using data corresponding to an integrated luminosity of 1.02 fb{sup -1} collected with the ATLAS detector. Using leptonic decays of oppositely charged W bosons, the total measured cross section is {sigma}(pp {yields} WW) = 54.4 {+-} 4.0 (stat.) {+-} 3.9 (syst.) {+-} 2.0 (lumi.) pb, consistent with the Standard Model prediction of {sigma}(pp {yields} 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.
