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′νℓ″ν and ZZ → 2ℓ2ℓ′, where ℓ = e, μ 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.
