EnglishThe WZ production cross section is measured by the CMS experiment at the CERN LHC in proton–proton collision data samples corresponding to integrated luminosities of 4.9fb−1 collected at √s=7TeV, and 19.6fb−1 at √s=8TeV. 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<mZ<111GeV are σ(pp→WZ; √s=7TeV)=20.14±1.32(stat)±0.38(theo)±1.06(exp)±0.44(lumi)pb and σ(pp→WZ; √s=8TeV)=24.09±0.87(stat)±0.80(theo)±1.40(exp)±0.63(lumi)pb. Differential cross sections with respect to the Z boson pT, the leading jet pT, and the number of jets are obtained using the √s=8TeV data. The results are consistent with standard model predictions and constraints on anomalous triple gauge couplings are obtained.

| Abstract: | The WZ production cross section is measured by the CMS experiment at the CERN LHC in proton–proton collision data samples corresponding to integrated luminosities of 4.9fb−1 collected at √s=7TeV, and 19.6fb−1 at √s=8TeV. 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<mZ<111GeV are σ(pp→WZ; √s=7TeV)=20.14±1.32(stat)±0.38(theo)±1.06(exp)±0.44(lumi)pb and σ(pp→WZ; √s=8TeV)=24.09±0.87(stat)±0.80(theo)±1.40(exp)±0.63(lumi)pb. Differential cross sections with respect to the Z boson pT, the leading jet pT, and the number of jets are obtained using the √s=8TeV data. The results are consistent with standard model predictions and constraints on anomalous triple gauge couplings are obtained. | |
