Abstract

A measurement is presented of the ZZ production cross section in the ZZ → 2ℓ2ℓ′ decay mode with ℓ = e, μ and ℓ′ = e, μ, τ in proton-proton collisions at √s=7 TeV with the CMS experiment at the LHC. Results are based on data corresponding to an integrated luminosity of 5.0 fb-1. The measured cross section σ(pp→ZZ)=6.24-0.80 +0.86stat. -0.32 +0.41(syst)± 0.14(lumi)pb is consistent with the standard model predictions. The following limits on ZZZ and ZZγ anomalous trilinear gauge couplings are set at 95% confidence level: -0.011<f4 Z<0.012,-0.012<f5 Z<0.012,-0.013<f4 γ}<0.015, and -0.014<f5 γ<0.014.[Figure not available: see fulltext.]
