Abstract
An inclusive measurement of the View the MathML source production cross section in pp collisions at View the MathML source 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 source and absolute pseudorapidity in the range |η|<1.44. The measured View the MathML source production cross section, 52.7±2.1 (stat)±6.4 (syst)±1.4 (lumi) fb, agrees well with the standard model prediction of View the MathML source. 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.
