Title: Measurement of the Z γ ν ν γ production cross section in pp collisions at s = 8 TeV and limits on anomalous ZZγ and Zγγ trilinear gauge boson couplings

Abstract

An inclusive measurement of the Zγ→$$ν\overline{ν}$$γ production cross section in pp collisions at $$\sqrt{s}=$$ 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→$$ν\overline{ν}$$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$$+2.4\atop{₋2.2}$$ fb . As a result, 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.
