Book Synopsis Measurement of the Pp 2!ZZ Production Cross Section and Constraints on Anomalous Triple Gauge Couplings in Four-lepton Final States at [arrow]" by :
Book excerpt: A measurement of the inclusive ZZ production cross section and constraints on anomalous triple gauge couplings in proton-proton collisions at [arrow]" = 8 TeV are presented. The analysis is based on a data sample, corresponding to an integrated luminosity of 19.6 fb−1, collected with the CMS experiment at the LHC. The measurements are performed in the leptonic decay modes ZZ 2!lll'l', where l = e, [mu] and l' = e, [mu], [tau]. The measured total cross section [sigma](pp 2!ZZ) = 7.7 " 0.5 (stat)-0.4+0.5 (syst) " 0.4 (theo) " 0.2 (lumi) pb, for both Z bosons produced in the mass range 60
