Observation of a new boson with mass near 125 GeV in pp collisions at √s = 7 and 8 TeV
(2013-06-20)
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 ...
Measurement of the W boson helicity in events with a single reconstructed top quark in pp collisions at √s = 8 TeV
(2015-01-12)
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 ...
Measurement of the tt¯ production cross section in the all-jet final state in pp collisions at √s = 7 TeV
(2013-05-14)
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 ...
Inclusive b-hadron production cross section with muons in pp collisions at √s = 7 TeV
(2011-03-18)
A measurement of the b-hadron production cross section in proton-proton collisions at √s = 7TeV is presented. The dataset, corresponding to 85 nb−1, was recorded with the CMS experiment at the LHC using a low-threshold ...
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 ...
Measurements of inclusive W and Z cross sections in pp collisions at √s = 7 TeV
(2011-01-19)
Measurements of inclusive W and Z boson production cross sections in pp collisions at √s = 7 TeV are presented, based on 2.9 pb−1 of data recorded by the CMS detector at the LHC. The measurements, performed in the electron ...
