Abstract

An inclusive measurement of the Zγ→νν‾γ production cross section in pp collisions at √s = 8 TeV is presented, using data corresponding to an integrated luminosity of 19.6fb−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→νν‾γ 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+2.4−2.2fb. 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.
