Measurement of W<sup>+</sup>W¯ production in pp collisions at √s = 7 TeV with the ATLAS detector and limits on anomalous WWZ and WWγ couplings

This paper presents a measurement of the W<SUP>+</SUP>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<sup>-1</sup> collected with the ATLAS detector at the Larg...

description This paper presents a measurement of the W<SUP>+</SUP>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<sup>-1</sup> collected with the ATLAS detector at the Large Hadron Collider. The W<SUP>+</SUP>W¯ production cross section σ(pp→W<SUP>+</SUP>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<SUP>+2.1</SUP><SUB>-1.9</SUB> 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.
