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 ...
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 ...
Measurement of the t-channel single-top-quark production cross section and of the |Vtb| CKM matrix element in pp collisions at √s = 8 TeV
(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 ...
