| dc.description.abstract | Measurements of the ZZ ZZ production cross sections in proton–proton collisions at center-of-mass energies of 7 and 8 TeV TeV are presented. Candidate events for the leptonic decay mode ZZ→2l2νZZ→2l2ν , where ll denotes an electron or a muon, are reconstructed and selected from data corresponding to an integrated luminosity of 5.1 (19.6) fb-1fb-1 at 7 (8) TeV TeV collected with the CMS experiment. The measured cross sections, σ(pp→ZZ)=5.1+1.5−1.4(stat)+1.4−1.1(syst)±0.1(lumi)~pbσ(pp→ZZ)=5.1−1.4+1.5(stat)−1.1+1.4(syst)±0.1(lumi)~pb at 7 TeV TeV , and 7.2+0.8−0.8(stat)+1.9−1.5(syst)±0.2(lumi)~pb7.2−0.8+0.8(stat)−1.5+1.9(syst)±0.2(lumi)~pb at 8 TeV TeV , are in good agreement with the standard model predictions with next-to-leading-order accuracy. The selected data are analyzed to search for anomalous triple gauge couplings involving the ZZ ZZ final state. In the absence of any deviation from the standard model predictions, limits are set on the relevant parameters. These limits are then combined with the previously published CMS results for ZZ ZZ in 4 ll final states, yielding the most stringent constraints on the anomalous couplings. | en_US |
| dc.description.sponsorship | We wish to thank our theoretician colleague Tobias Kasprzik for providing the numerical calculations of the next-to-leading-order electroweak corrections to the ZZ and WZ processes. We congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort. In addition, we gratefully acknowledge the computing centers and personnel of the Worldwide LHC Computing Grid for delivering so effectively the computing infrastructure essential to our analyses.
