Abstract: A measurement of the inclusive ZZ production cross section and constraints on anomalous triple gauge couplings in proton–proton collisions at vs=8 TeV are presented. The analysis is based on a data sample, corresponding to an integrated luminosity of 19.6fb-1, collected with the CMS experiment at the LHC. The measurements are performed in the leptonic decay modes ZZ ? lll’l’, where l =e, µand ll=e, µ, t. The measured total cross section s(pp ?ZZ) =7.7 ±0.5(stat)+0.5-0.4(syst)±0.4 (theo) ±0.2(lumi) pb, for both Z bosons produced in the mass range 60
