Abstract

In this thesis a measurement of WZ production cross section is presented. Total and differential cross sections are measured by the CMS experiment at the CERN LHC in proton-proton collision data samples corresponding to an integrated luminosity of 19:6 fb−1 at √s = 8 TeV. The measurements are performed using the fully-leptonic WZ decay modes with electrons and muons in the final state. The measured total cross section for 71 < mZ < 111 GeV is σ(pp→WZ) = 24:09±0:87( stat.)±1:62(... More syst.)±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. The results are consistent with standard model predictions. Less
