Title: Measurement of the W +W - cross section in √s = 7 TeV pp collisions with ATLAS

Abstract

This Letter presents a measurement of the W +W - production cross section in √s = 7 TeV pp collisions by the ATLAS experiment, using 34 inverse pb -1 of integrated luminosity produced by the Large Hadron Collider at CERN. Selecting events with two isolated leptons, each either an electron or a muon, 8 candidate events are observed with an expected background of 1.7±0.6 events. The measured cross section is 41 +20 -16(stat) ± 5(syst) ± 1(lumi) pb, which is consistent with the standard model prediction of 44 ± 3 pb calculated at next-to-leading order in QCD.
