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 fb^(−1). The measurements are performed in the leptonic decay modes W^+W^− → ℓ'vℓ"ν and ZZ → 2ℓ2ℓ', where ℓ = e,μ,τ and ℓ'(ℓ") = e,μ,τ . The measured cross sections σ(pp → W^+W^− = 69.9±2.8(stat.)±5.6(syst.)±3.1(lum.) pb and σ(pp→ZZ) = 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.
