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 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 ...
Event activity dependence of Υ(nS) production in √SNN = 5.02 TeV pPb and √s = 2.76 TeV pp collisions
(2014-04-15)
The production of Y (1S), Y (2S), and Y (3S) is investigated in pPb and pp collisions at centre-of-mass energies per nucleon pair of 5.02 TeV and 2.76 TeV, respectively. The datasets correspond to integrated luminosities ...
Search for baryon number violation in top-quark decays
(2014-04-04)
A search for baryon number violation (BNV) in top-quark decays is performed using pp collisions
produced by the LHC at √s = 8 TeV. The top-quark decay considered in this search results in one
light lepton (muon or ...
