Abstract

An inclusive measurement of the Zγ → ννγ production cross section in pp collisions at √s = 8 TeV is presented, using data corresponding to an integrated luminosity of 19.6 fb^(−1) collected with the CMS detector at the LHC. This measurement is based on the observation of events with large missing energy and with a single photon with transverse momentum above 145 GeV and absolute pseudorapidity in the range |η|<1.44. The measured Zγ → ννγ production cross section, 52.7±2.1 (stat)±6.4 (syst)±1.4 (lumi) fb, agrees well with the standard model prediction of 50.0_(−2.2)^(+2.4) fb. A study of the photon transverse momentum spectrum yields the most stringent limits to date on the anomalous ZZγ and Zγγ trilinear gauge boson couplings.
