英文摘要	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 root s = 8 tev. the z bosons 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 19.7 fb(-1). the electroweak contribution has a significance of 3.0 standard deviations, and the measured fiducial cross section is 1.86(-0.75)(+0.90)(stat)(-0.26)(+0.34)(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(-1.35)(+1.53) (stat)(-0.37)(+0.43)(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 z gamma mass distribution.
