The measurements are performed using the fully-leptonic WZ decay modes with electrons and muons in the final state. The measured cross sections for $71< m_{\mathrm{Z}} < 111\,\text{GeV} $ are $\sigma ({\mathrm{p}\mathrm{p}}\rightarrow {\mathrm{W}\mathrm{Z}},~\sqrt{s} = 7\,\text{TeV}) = 20.14 \pm 1.32\,\text{(stat)} \pm 0.38\,\text{(theo)} \pm 1.06\,\text{(exp)} \pm 0.44\,\text{(lumi)} $ $\,\text{pb}$ and $\sigma ({\mathrm{p}\mathrm{p}}\rightarrow {\mathrm{W}\mathrm{Z}},~\sqrt{s} = 8\,\text{TeV}) = 24.09 \pm 0.87\,\text{(stat)} \pm 0.80\,\text{(theo)} \pm 1.40\,\text{(exp)} \pm 0.63\,\text{(lumi)} $ $\,\text{pb}$ . Differential cross sections with respect to the $\mathrm{Z}$ boson $p_{\mathrm{T}}$ , the leading jet $p_{\mathrm{T}}$ , and the number of jets are obtained using the $\sqrt{s} = 8\,\text{TeV} $ data. The results are consistent with standard model predictions and constraints on anomalous triple gauge couplings are obtained.engjournal article2019-02-04
