Search for resonances in the dilepton mass distribution in pp collisions at √s = 7TeV
(2011-05-19)
A search for narrow resonances at high mass in the dimuon and dielectron channels has been performed by the CMS experiment at the CERN LHC, using pp collision data recorded at √s = 7 TeV. The event samples correspond to ...
Long-range and short-range dihadron angular correlations in central PbPb collisions at psNN = 2:76 TeV
(2011-07-18)
First measurements of dihadron correlations for charged particles are presented for central PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV over a broad range in relative pseudorapidity (∆η) and the ...
Measurement of the mass difference between top and antitop quarks
(2012-06-19)
A measurement of the mass difference between the top and the antitop quark (Δmt = mt − mt¯) is performed using events with a muon or an electron and at least four jets in the final state. The analysis is based on data ...
Shape, transverse size, and charged-hadron multiplicity of jets in pp collisions at √s = 7 TeV
(2012-06-27)
Measurements of jet characteristics from inclusive jet production in protonproton collisions at a centre-of-mass energy of 7 TeV are presented. The data sample was collected with the CMS detector at the LHC during 2010 and ...
Measurement of the Z/γ*+b-jet cross section in pp collisions at √s = 7 TeV
(2012-06-22)
The production of b jets in association with a Z/γ* boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV and recorded by the CMS detector. The inclusive cross section for ...
Search for supersymmetry in final states with missing transverse energy and 0, 1, 2, or ≥3 b-quark jets in 7 TeV pp collisions using the variable α T
(2013-01-10)
A search for supersymmetry in final states with jets and missing transverse energy is performed in pp collisions at a centre-of-mass energy of √s = 7 TeV. The data sample corresponds to an integrated luminosity of 4.98 ...
Measurement of the X(3872) production cross section via decays to J/ψπ+π− in pp collisions at √s = 7 TeV
(2013-04-29)
The production of the X(3872) is studied in pp collisions at √s = 7 TeV, using decays to J/ψπ+π−, where the J/ψ decays to two muons. The data were recorded by the CMS experiment and correspond to an integrated luminosity ...
Search for microscopic black holes in pp collisions at √s = 7 TeV

A search for microscopic black holes in pp collisions at a center-of-mass energy of 7 TeV is presented. The data sample corresponds to an integrated luminosity of 4.7 fb−1 recorded by the CMS experiment at the LHC in 2011. ...
Search for a light charged Higgs boson in top quark decays in pp collisions at √s = 7 TeV
(2012-07-24)
Results are presented on a search for a light charged Higgs boson that can be produced in the decay of the top quark t → H+b and which, in turn, decays into τ+ντ . The analysed data correspond to an integrated luminosity ...
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 ...
