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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
