Measurement of the W ± Z boson pair-production cross section in pp collisions at s=13 TeV with the ATLAS detector

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 in...
