Erratum: Measurement of W^{+}W^{-} production in pp collisions at sqrt[s]=7 TeV with the ATLAS detector and limits on anomalous WWZ and WWγ couplings [Phys. Rev. D 87, 112001 (2013)] (original) (raw)

This paper presents a measurement of the W þ W À production cross section in pp collisions at ffiffi ffi s p ¼ 7 TeV. The leptonic decay channels are analyzed using data corresponding to an integrated luminosity of 4:6 fb À1 collected with the ATLAS detector at the Large Hadron Collider. The W þ W À production cross section ðpp ! W þ W À þ XÞ is measured to be 51:9 AE 2:0ðstatÞ AE 3:9ðsystÞ AE 2:0ðlumiÞ pb, compatible with the Standard Model prediction of 44:7 þ2:1 À1:9 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 WW couplings.
