Search for top-squark pairs decaying into Higgs or Z bosons in pp collisions at √s=8 TeV
(2014-09-07)
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 ...
Study of exclusive two-photon production of W+W- in pp collisions at √s=7 TeV and constraints on anomalous quartic gauge couplings
(2013-07-18)
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. ...
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 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 ...
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 ...
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 ...
