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 ...

A search for exclusive or quasi-exclusive W+W− production by photon-photon interactions, pp → p(*)W+W−p(*), at √s = 7 TeV is reported using data collected by the CMS detector with an integrated luminosity of 5.05 fb−1. ...

A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample ...

A measurement of the W boson helicity is presented, where the W boson originates from the decay of a top quark produced in pp collisions. The event selection, optimized for reconstructing a single top quark in the final ...

A measurement is presented of the tt¯ production cross section (σtt¯) in proton-proton collisions at a centre-of-mass energy of 7 TeV, in the all-jet final state that contains at least six jets, two of which are tagged ...

A search is performed for a massive new vector-like quark T, with charge 2 3 , that is pair produced together with its antiparticle in proton–proton collisions. The data were collected by the CMS experiment at the Large ...

The first direct search for lepton-flavour-violating decays of the recently discovered Higgs boson (H) is described. The search is performed in the H → μτe and H → μτh channels, where τe and τh are tau leptons reconstructed ...

A search for pair production of neutral color-octet weak-triplet scalar particles ( 0) is performed in processes where one 0 decays to a pair of b quark jets and the other to a Z boson plus a jet, with the Z boson ...

Yields of prompt and non-prompt J/ψ, as well as Υ (1S) mesons, are measured by the CMS experiment via their μ+μ− decays in PbPb and pp collisions at √sNN = 2.76 TeV for quarkonium rapidity |y| < 2.4. Differential cross ...

A search is reported for the standard model Higgs boson in the H → ZZ → ℓ+ℓ−τ +τ − decay mode, where ℓ = μ or e, in proton-proton collisions at √s =7 TeV, corresponding to an integrated luminosity of 4.7 fb−1 collected ...
