(2014-06-16)
Measurements are presented of the t-channel single-top-quark production cross section in proton-proton collisions at √s = 8 TeV. The results are based on a data sample corresponding to an integrated luminosity of 19.7 ...
Measurement of the λb 0 lifetime in pp collisions at √s = 7 TeV
(2013-07-26)
A measurement of the Λ0b lifetime using the decay Λ0b→J/ψΛ in protonproton collisions at √s = 7 TeV is presented. The data set, corresponding to an integrated luminosity of about 5 fb−1, was recorded with the CMS experiment ...
Search for heavy quarks decaying into a top quark and a W or Z boson using lepton + jets events in pp collisions at √s = 7 TeV
(2013-01-24)
Results are presented from a search for the pair-production of heavy quarks, QQ¯ , that decay exclusively into a top quark and a W or Z boson. The search is performed using a sample of proton-proton collisions at √s = 7 ...
Search for new physics in events with same-sign dileptons and b-tagged jets in pp collisions at √s = 7 TeV
(2012-08-22)
A search for new physics is performed using isolated same-sign dileptons with at least two b-quark jets in the final state. Results are based on a 4.98 fb−1 sample of proton-proton collisions at a centre-of-mass energy of ...
Event activity dependence of Υ(nS) production in √SNN = 5.02 TeV pPb and √s = 2.76 TeV pp collisions
(2014-04-15)
The production of Y (1S), Y (2S), and Y (3S) is investigated in pPb and pp collisions at centre-of-mass energies per nucleon pair of 5.02 TeV and 2.76 TeV, respectively. The datasets correspond to integrated luminosities ...
Search for electroweak production of charginos and neutralinos using leptonic final states in pp collisions at √s = 7 TeV
(2012-11-27)
The 2011 dataset of the CMS experiment, consisting of an integrated luminosity of 4.98 fb−1 of pp collisions at √s = 7 TeV, enables expanded searches for direct electroweak pair production of charginos and neutralinos ...
Search for baryon number violation in top-quark decays
(2014-04-04)
A search for baryon number violation (BNV) in top-quark decays is performed using pp collisions
produced by the LHC at √s = 8 TeV. The top-quark decay considered in this search results in one
light lepton (muon or ...
Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies

Measurements of two-particle angular correlations between an identified strange hadron (K0
S or Λ/Λ)
and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity
and full azimuth. ...
Search for the standard model Higgs boson produced in association with a top-quark pair in pp collisions at the LHC
(2013-05-28)
A search for the standard model Higgs boson produced in association with a top-quark pair is presented using data samples corresponding to an integrated luminosity of 5.0 fb−1 (5.1 fb−1) collected in pp collisions at the ...
Search for heavy bottom-like quarks in 4.9 fb-1 of pp collisions at √s = 7 TeV
(2012-05-25)
Results are presented from a search for heavy bottom-like quarks, pair-produced in pp collisions at √s = 7 TeV, undertaken with the CMS experiment at the LHC. The b′ quarks are assumed to decay exclusively to tW. The ...
