Abstract: A measurement of the VZ (V=W,Z) production cross section in proton-proton collisions at √s=8 TeV in the VZ →Vbˉb decay mode with, Z→νˉν, W→ℓν and Z→ℓℓ (ℓ=e,μ) is presented. The results are based on data corresponding to an integrated luminosity of 18.9 fb−1 collected with the CMS experiment at the Large Hadron Collider. The process is observed with a significance exceeding six standard deviations. The cross sections are determined to be σ(pp→WZ)=30.7±9.3(stat.)±7.1(syst.)±4.1(theo.)±1.0(lumi.)pb and σ(pp→ZZ)=6.5±1.7(stat.)±1.0(syst.)±0.9(theo.)±0.2(lumi.)pb, for the Z bosons produced in the mass region < M_{\mathrm{Z}} < 120$ GeV. Both values are consistent with the predictions of next-to-leading order quantum chromodynamics calculations. | ||
