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 ...
Evidence for the 125 gev higgs boson decaying to a pair of τ leptons
(2014-05)
A search for a standard model Higgs boson decaying into a pair of τ leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 ...
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 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 ...
