Abstract:

The production of W ± Z events in proton–proton collisions at a centre-of-mass energy of 13 TeV is measured with the ATLAS detector at the LHC. The collected data correspond to an integrated luminosity of 3.2 fb −1 . The W ± Z candidates are reconstructed using leptonic decays of the gauge bosons into electrons or muons. The measured inclusive cross section in the detector fiducial region for leptonic decay modes is σ W ± Z→ℓ ′ νℓℓ fid. =63.2±3.2(stat.)±2.6(sys.)±1.5(lumi.) fb. In comparison, the next-to-leading-order Standard Model prediction is 53.4 −2.8 +3.6 fb. The extrapolation of the measurement from the fiducial to the total phase space yields σ W ± Z tot. =50.6±2.6(stat.)±2.0(sys.)±0.9(th.)±1.2(lumi.) pb, in agreement with a recent next-to-next-to-leading-order calculation of 48.2 −1.0 +1.1 pb. The cross section as a function of jet multiplicity is also measured, together with the charge-dependent W + Z and W − Z cross sections and their ratio. © 2016 The Author(s)
