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 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 ...
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 ...
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 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 ...
Inclusive b-jet production in pp collisions at √s = 7 TeV
(2012-04-17)
The inclusive b-jet production cross section in pp collisions at a center-of mass energy of 7 TeV is measured using data collected by the CMS experiment at the LHC. The cross section is presented as a function of the jet ...
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 ...
