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.] © 2013 CERN for the benefit of the CMS collaboration.Springer Verlag2013Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/15947https://doi.org/10.1007/jhep01(2013)0631126-6708enJournal of High Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/15947
