| Abstract: | An inclusive measurement of the View the MathML sourceZγ→νν‾γ production cross section in pppp collisions at View the MathML sources=8TeV 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 145View the MathML sourceGeV and absolute pseudorapidity in the range |η|<1.44|η|<1.44. The measured View the MathML sourceZγ→νν‾γ production cross section, 52.7±2.1 (stat)±6.4 (syst)±1.4 (lumi) fb52.7±2.1 (stat)±6.4 (syst)±1.4 (lumi) fb, agrees well with the standard model prediction of View the MathML source50.0−2.2+2.4 fb. A study of the photon transverse momentum spectrum yields the most stringent limits to date on the anomalous ZZγZZγ and ZγγZγγ trilinear gauge boson couplings. |
