Results are based on data corresponding to an integrated luminosity of 5.0 fb−1. The measured cross section σ(pp→ZZ)=6.24+0.86−0.80(stat.)+0.41−0.32(syst.)±0.14(lumi.)pbσ(pp→ZZ)=6.24−0.80+0.86(stat.)−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<fZ4<0.012,−0.012<fZ5<0.012,−0.013<fγ4<0.015−0.011<f4Z<0.012,−0.012<f5Z<0.012,−0.013<f4γ<0.015, and −0.014<fγ5<0.014−0.014<f5γ<0.014.Article10.1007/JHEP01(2013)063https://orcid.org/0000-0002-3932-3769openAccess
