Charged-particle nuclear modification factors in PbPb and pPb collisions at root s(NN)=5.02 TeV
(Springer International Publishing, 2017)The spectra of charged particles produced within the pseudorapidity window |η| < 1 at sNN−−−−√=5.02sNN=5.02 TeV are measured using 404 μb−1 of PbPb and 27.4 pb−1 of pp data collected by the CMS detector at the LHC in ... -
Charged-particle nuclear modification factors in XeXe collisions at √sNN=5.44 TeV
(Springer Nature, 2018-10)The differential yields of charged particles having pseudorapidity within vertical bar eta vertical bar < 1 are measured using xenon-xenon (XeXe) collisions at root S-NN = 5.44 TeV. The data, corresponding to an integrated ... -
Decomposing transverse momentum balance contributions for quenched jets in PbPb collisions at √=2.76sNN=2.76 TeV
(Springer International Publishing, 2016)Interactions between jets and the quark-gluon plasma produced in heavy ion collisions are studied via the angular distributions of summed charged-particle transverse momenta (pT) with respect to both the leading and ... -
In-medium modification of dijets in PbPb collisions at √sNN = 5.02 TeV
(Springer, 2021-05-14)Modifications to the distribution of charged particles with respect to high transverse momentum (pT) jets passing through a quark-gluon plasma are explored using the CMS detector. Back-to-back dijets are analyzed in lead-lead ... -
Measurement of Bs 0 meson production in pp and PbPb collisions at sNN=5.02 TeV
(Elsevier, 2019-09-10)The production cross sections of B-s(0) mesons and charge conjugates are measured in proton-proton (pp) and PbPb collisions via the exclusive decay channel B-s(0)-> J/ psi phi ->mu(+) mu(-) K+K- at a center-of-mass energy ... -
Measurement of transverse momentum relative to dijet systems in PbPb and pp collisions at 2.76 TeV
(Springer International Publishing, 2016-01)An analysis of dijet events in PbPb and pp collisions is performed to explore the properties of energy loss by partons traveling in a quark-gluon plasma. Data are collected at a nucleon-nucleon center-of-mass energy of ... -
Observation of B0 s mesons and measurement of the B0 s /B+ yield ratio in PbPb collisions at √snn = 5.02 TeV
(Elsevier, 2022-06-10)The Bs 0 and B+ production yields are measured in PbPb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV. The data sample, collected with the CMS detector at the LHC, corresponds to an integrated luminosity ...
