Measurements of the pp $\to$ WZ inclusive and differential production cross section and constraints on charged anomalous triple gauge couplings at $\sqrt{s}=$ 13 TeV

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 ${\sigma }_{\text{tot}}$(pp $\to$ WZ$)$ = 48.09 ${}_{-0.96}^{+1.00}$ (stat) ${}_{-0.37}^{+0.44}$ (theo) ${}_{-2.17}^{+2.39}$ (syst) $\pm$ 1.39 (lumi) 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 $p_{\mathrm{T}}$, the leading jet $p_{\mathrm{T}}$, 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 $p_{\mathrm{T}}$, 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.
