Abstract
The nuclear modification factors of J/ψ and
ψ(2S) mesons are measured in PbPb collisions at a centre-of mass energy per nucleon pair of √sNN = 5.02 TeV. The anal ysis is based on PbPb and pp data samples collected by CMS
at the LHC in 2015, corresponding to integrated luminosities
of 464μb−1 and 28 pb−1, respectively. The measurements
are performed in the dimuon rapidity range of |y| < 2.4 as
a function of centrality, rapidity, and transverse momentum
(pT) from pT = 3 GeV/c in the most forward region and
up to 50 GeV/c. Both prompt and nonprompt (coming from
b hadron decays) J/ψ mesons are observed to be increas ingly suppressed with centrality, with a magnitude similar
to the one observed at √sNN = 2.76 TeV for the two J/ψ
meson components. No dependence on rapidity is observed
for either prompt or nonprompt J/ψ mesons. An indication
of a lower prompt J/ψ meson suppression at pT > 25 GeV/c
is seen with respect to that observed at intermediate pT. The
prompt ψ(2S) meson yield is found to be more suppressed
than that of the prompt J/ψ mesons in the entire pT range.
