Abstract: (APS)

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 44.7-1.9+2.1 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.

The ATLAS reference system is a Cartesian right-handed coordinate system with its origin at the nominal interac- tion point (IP) in the center of the detector and the z-axis along the beam direction. The x -axis points from the IP to the center of the LHC ring, and the y -axis points up- ward. Cylindrical coordinates ( r; ) are used in the trans- verse plane, being the azimuthal angle around the beam direction. The pseudorapidity is dened in terms of the polar angle as = ln tan( = 2). Transverse momen- tum ( p T ) is dened relative to the beam axis.
