A search for new resonances decaying to WW, ZZ, or WZ is presented. Final states are considered in which one of the vector bosons decays leptonically and the other hadronically. Results are based on data corresponding to an integrated luminosity of 19.7 …

Abstract The production of the X(3872) is studied in pp collisions at $ \sqrt{s}=7 $ TeV, using decays to J/ψπ+π−, where the J/ψdecays to two muons. The data were recorded by the CMS experiment and correspond to an integrated luminosity of 4.8 …

Abstract A search is performed for long-lived neutral particles decaying into a photon and invisible particles. An example of such a signature is the decay of the lightest neutralino with nonzero lifetime into a gravitino and a photon in gauge-mediated supersymmetry, with …

A measurement of inclusive W and Z production cross sections in pp collisions at sqrt(s)=7 TeV is presented. The electron and muon decay channels are analyzed in a data sample collected with the CMS detector at the LHC and corresponding to an …
