Abstract
The WZ production cross section is measured in proton-proton collisions at a centre-of-mass energy \sqrt{s} = 13 TeV using data collected with the CMS detector, corresponding to an integrated luminosity of 35.9 fb^{-1}. The inclusive cross section is measured to be σ_{tot}(pp → WZ) = 48.09^{+1.00}_{-0.96}(stat)^{+0.44}_{-0.37}(theo)±1.39(lum) pb, resulting in a total uncertainty of −2.78/+2.98 pb. Fiducial cross section and ratios of charge-dependent cross section measurements are provided. Differential cross section measurements are also presented with respect to three variables: the Z boson transverse momentum p_{T}, the leading jet p_{T}, and the M(WZ) variable, defined as the invariant mass of the system composed of the three leptons and the missing transverse momentum. Differential measurements with respect to the W boson p_{T}, separated by charge, are also shown. Results are consistent with standard model predictions, favouring next-to-next-to-leading-order predictions over those at next-to-leading order. Constraints on anomalous triple gauge couplings are derived via a binned maximum likelihood fit to the M(WZ) variable.
