Measurement of W gamma and Z gamma production in proton-proton collisions at root s=7 TeV with the ATLAS detector

Abstract:

A study of W ±Z production in proton-proton collisions at √s = 7 TeV is presented using data corresponding to an integrated luminosity of 4. 6 fb -1 collected with the ATLAS detector at the Large Hadron Collider in 2011. In total, 317 candidates, with a background expectation of 68±10 events, are observed in double-leptonic decay final states with electrons, muons and missing transverse momentum. The total cross-section is determined to be σ WZ tot = 19. 0 -1.3 +1.4(stat.)±0.9(syst.)±0.4(lumi...
