| dc.description.abstract | A measurement is presented of the cross section for the electroweak production of a Z boson and a photon in association with two jets in proton–proton collisions at √s=8TeV. The Zbosons are identified through their decays to electron or muon pairs. The measurement is based on data collected with the CMS detector corresponding to an integrated luminosity of 19.7fb−1. The electroweak contribution has a significance of 3.0 standard deviations, and the measured fiducial cross section is 1.86+0.90−0.75(stat)+0.34−0.26(syst)±0.05 (lumi)fb, while the summed electroweak and quantum chromodynamic total cross section in the same region is observed to be 5.94+1.53−1.35(stat)+0.43−0.37(syst)±0.13 (lumi)fb. Both measurements are consistent with the leading-order standard model predictions. Limits on anomalous quartic gauge couplings are set based on the Zγmass distribution. | en_US |
