Abstract

The W+W and ZZ production cross sections are measured in proton–proton collisions at s=8 TeV with the CMS experiment at the LHC in data samples corresponding to an integrated luminosity of up to 5.3 fb1. The measurements are performed in the leptonic decay modes W+Wνν and ZZ22, where =e,μ and ()=e,μ,τ. The measured cross sections σ(ppW+W)=69.9±2.8(stat.)±5.6(syst.)±3.1(lum.) pb and σ(ppZZ)=8.4±1.0(stat.)±0.7(syst.)±0.4(lum.) pb, for both Z bosons produced in the mass region 60<mZ<120 GeV, are consistent with standard model predictions. These are the first measurements of the diboson production cross sections at s=8 TeV.
