| Abstract: The WZ production cross section is measured in proton-proton collisions using 35.9 fb$^{-1}$ of data collected with the CMS detector. An estimate of the inclusive cross section yields a result of $\sigma_{\textrm{tot}}(\mathrm{pp} \rightarrow \mathrm{WZ}) = $ 48.09 $^{+1.00}_{-0.96}$ (stat) $^{+0.44}_{-0.37}$ (theo) $^{+2.39}_{-2.17}$ (syst) $\pm$ 1.39 (lumi) pb, for a total uncertainty of $-2.78$ and $+2.98$ pb. Fiducial and charge asymmetry measurements are provided. Differential cross section measurements are also presented with respect to three variables: the Z boson $p_{\mathrm{T}}$, the leading jet $p_{\mathrm{T}}$, and the $M_{\mathrm{WZ}}$ 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 $p_{\mathrm{T}}$, split by charge, are also shown. Results are consistent with standard model predictions, favouring next-to-next-to-leading-order calculations. Constraints on anomalous triple gauge couplings are derived via a binned maximum likelihood fit to the $M_{\mathrm{WZ}}$ variable. | ||
