Observation of long-range, near-side angular correlations in proton-proton collisions at the LHC
(2010-09-27)
Results on two-particle angular correlations for charged particles emitted in proton-proton collisions at center-of-mass energies of 0.9, 2.36, and 7 TeV are presented, using data collected with the CMS detector over a ...
Measurement of BB̄ angular correlations based on secondary vertex reconstruction at √s = 7 TeV
(2011-03-28)
A measurement of the angular correlations between beauty and anti-beauty hadrons (BB¯) produced in pp collisions at a centre-of-mass energy of 7 TeV at the CERN LHC is presented, probing for the first time the region of ...
Modification of jet shapes in PbPb collisions at √sNN=2.76TeV
(2014-03-07)
The first measurement of jet shapes, defined as the fractional transverse momentum radial distribution, for inclusive jets produced in heavy-ion collisions is presented. Data samples of PbPb and pp collisions, corresponding ...
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
(2012-04-12)
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 ...
