AB  - An inclusive measurement of the Z gamma - GT nu(nu) over bar gamma production cross section in pp collisions at root 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 vertical bar eta vertical bar LT 1.44. The measured Z gamma - GT nu LT (nu)over bar GT gamma 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 ZZ gamma and Z gamma gamma trilinear gauge boson couplings. (C) 2016 The Author(s).

AB  - A study of vector boson scattering in pp collisions at a center-of-mass energy of 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.4 fb(-1) collected with the CMS detector. Candidate events are selected with exactly two leptons of the same charge, two jets with large rapidity separation and high dijet mass, and moderate missing transverse energy. The signal region is expected to be dominated by electroweak same-sign W-boson pair production. The observation agrees with the standard model prediction. The observed significance is 2.0 standard deviations, where a significance of 3.1 standard deviations is expected based on the standard model. Cross section measurements for (WW +/-)-W-+/- and WZ processes in the fiducial region are reported. Bounds on the structure of quartic vector-boson interactions are given in the framework of dimension-eight effective field theory operators, as well as limits on the production of doubly charged Higgs bosons.

AB  - Results are presented from a search for new decaying massive particles whose presence is inferred from an imbalance in transverse momentum and which are produced in association with a single top quark that decays into a bottom quark and two light quarks. The measurement is performed using 19.7 fb(-1) of data from proton-proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS detector at the CERN LHC. No deviations from the standard model predictions are observed and lower limits are set on the masses of new invisible bosons. In particular, scalar and vector particles, with masses below 330 and 650 GeV, respectively, are excluded at 95% confidence level, thereby substantially extending a previous limit published by the CDF Collaboration.
