Measurement of the W+W- cross section in sqrt(s) = 7 TeV pp collisions with ATLAS

Abstract

This Letter presents a measurement of the $WW$ production cross section in $sqrt{s} = 7 TeV pp$ collisions by the ATLAS experiment, using 34 $pbi$ 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.
