Description
The prompt D0 meson azimuthal anisotropy coefficients,
v2 and v3, are measured at midrapidity (|y
|<1.0 ) in Pb-Pb collisions at a center-of-mass energy √{sN
N }=5.02 TeV per nucleon pair with data collected by the CMS
experiment. The measurement is performed in the transverse momentum
(pT ) range of 1 to 40 GeV /c , for central and midcentral
collisions. The v2 coefficient is found to be positive
throughout the pT range studied. The first measurement of the
prompt D0 meson v3 coefficient is performed, and
values up to 0.07 are observed for pT around 4 GeV /c .
Compared to measurements of charged particles, a similar pT
dependence, but smaller magnitude for pT <6 GeV /c , is
found for prompt D0 meson v2 and v3
coefficients. The results are consistent with the presence of collective
motion of charm quarks at low pT and a path length dependence
of charm quark energy loss at high pT , thereby providing new
constraints on the theoretical description of the interactions between
charm quarks and the quark-gluon plasma.
