Studies of dijet transverse momentum balance and pseudorapidity distributions in pPb collisions at √sNN= 5.02 TeV
Dijet production has been measured in pPb collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV. A data sample corresponding to an integrated luminosity of 35 nb−1was collected using the Compact Muon Solenoid ...
Search for standard model production of four top quarks in the lepton + jets channel in pp collisions at √s = 8 TeV
A search is presented for standard model (SM) production of four top quarks (Formula presented.) in pp collisions in the lepton + jets channel. The data correspond to an integrated luminosity of 19.6 fb−1 recorded at a ...
Search for top-squark pairs decaying into Higgs or Z bosons in pp collisions at √s=8 TeV
A search for supersymmetry through the direct pair production of top squarks, with Higgs (H) or Z bosons in the decay chain, is performed using a data sample of proton-proton collisions at s=8 TeV collected in 2012 with ...
Constraints on the Higgs boson width from off-shell production and decay to Z-boson pairs
Constraints are presented on the total width of the recently discovered Higgs boson, ΓH, using its relative on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays to an electron ...
Search for W′→tb decays in the lepton + jets final state in pp collisions at √s = 8TeV
Results are presented from a search for the production of a heavy gauge boson W′ decaying into a top and a bottom quark, using a data set collected by the CMS experiment at √s = 8TeV and corresponding to an integrated ...
Search for massive resonances decaying into pairs of boosted bosons in semi-leptonic final states at root s = 8 TeV
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 ...
Measurement of prompt J/ψ pair production in pp collisions at s = 7 Tev
Production of prompt J/ψ meson pairs in proton-proton collisions at s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb-1. The two J/ψ mesons ...
Measurement of the production cross sections for a Z boson and one or more b jets in pp collisions at √s = 7 TeV
The production of a Z boson, decaying into two leptons and produced in association with one or more b jets, is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV. The data were ...
