Abstract

This paper presents a measurement of the W+W− production cross section in pp collisions at s√=7  TeV. The leptonic decay channels are analyzed using data corresponding to an integrated luminosity of 4.6  fb−1 collected with the ATLAS detector at the Large Hadron Collider. The W+W− production cross section σ(pp→W+W−+X) is measured to be 51.9±2.0(stat)±3.9(syst)±2.0(lumi)  pb, compatible with the Standard Model prediction of 44.7+2.1−1.9  pb. A measurement of the normalized fiducial cross section as a function of the leading lepton transverse momentum is also presented. The reconstructed transverse momentum distribution of the leading lepton is used to extract limits on anomalous WWZ and WWγ couplings.
