abstract = {The elliptic flow of prompt and non-prompt J/ψ
was measured in the dimuon decay channel in Pb+Pb collisions
at
√
sNN
= 5.02 TeV with an integrated luminosity
of 0.42 nb−1 with the ATLAS detector at the LHC.
The prompt and non-prompt signals are separated using a
two-dimensional simultaneous fit of the invariant mass and
pseudo-proper decay time of the dimuon system from the
J/ψ decay. The measurement is performed in the kinematic
range of dimuon transverse momentum and rapidity
9 < pT < 30 GeV, |y| < 2, and 0–60% collision centrality.
The elliptic flow coefficient, v2, is evaluated relative to
the event plane and the results are presented as a function of
transverse momentum, rapidity and centrality. It is found that
prompt and non-prompt J/ψ mesons have non-zero elliptic
flow. Prompt J/ψ v2 decreases as a function of pT, while for
non-prompt J/ψ it is, with limited statistical significance,
consistent with a flat behaviour over the studied kinematic
region. There is no observed dependence on rapidity or centrality.},
