Measurement of the charge asymmetry in top quark pair production in pp collisions at √s = 8 TeV using a template method
(2016-02-18)
The charge asymmetry in the production of top quark and antiquark pairs is measured in proton-proton
collisions at a center-of-mass energy of 8 TeV. The data, corresponding to an integrated luminosity of
19.6 fb−1, were ...
Inclusive search for a vector-like T quark with charge 2/3 in pp collisions at √s=8 TeV
(2014-02-05)
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 ...
Observation of sequential Υ suppression in PbPb collisions
(2012-11-26)
The suppression of the individual ðnSÞ states in PbPb collisions with respect to their yields in pp data
has been measured. The PbPb and pp data sets used in the analysis correspond to integrated luminosities
of 150 b ...
Search for lepton-flavour-violating decays of the Higgs boson
(2015-10-07)
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 ...
Charged particle transverse momentum spectra in pp collisions at √s = 0:9 and 7 TeV
(2011-08-19)
The charged particle transverse momentum (pT) spectra are presented for pp collisions at √s = 0.9 and 7 TeV. The data samples were collected with the CMS detector at the LHC and correspond to integrated luminosities of ...

(2011-10-27)
A measurement of inclusive W and Z production cross sections in pp collisions at √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 ...
Search for neutral color-octet weak-triplet scalar particles in proton-proton collisions at √s = 8TeV
(2015-09-29)
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 ...
Suppression of non-prompt J/ψ, prompt J/ψ, and Y(1S) in PbPb collisions at √s NN = 2.76 TeV
(2012-05-14)
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 ...
Search for the standard model Higgs boson in the H → ZZ → ℓ+ℓ−τ+τ− decay channel in pp collisions at √s = 7 TeV
(2012-03-26)
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 ...
