Abstract: (Springer)

The inclusive J/ψ elliptic (v

_{2}

) and triangular (v

_{3}

) flow coefficients measured at forward rapidity (2.5 < y < 4) and the v

_{2}

measured at midrapidity (|y| < 0.9) in Pb-Pb collisions at

\sqrt{s_{\mathrm{NN}}}

= 5.02 TeV using the ALICE detector at the LHC are reported. The entire Pb-Pb data sample collected during Run 2 is employed, amounting to an integrated luminosity of 750 μb

^{−1}

at forward rapidity and 93 μb

^{−1}

at midrapidity. The results are obtained using the scalar product method and are reported as a function of transverse momentum p

_{T}

and collision centrality. At midrapidity, the J/ψ v

_{2}

is in agreement with the forward rapidity measurement. The centrality averaged results indicate a positive J/ψ v

_{3}

with a significance of more than 5σ at forward rapidity in the p

_{T}

range 2 < p

_{T}

< 5 GeV/c. The forward rapidity v

_{2}

, v

_{3}

, and v

_{3}

/v

_{2}

results at low and intermediate p

_{T}

(p

_{T}

≲ 8 GeV/c) exhibit a mass hierarchy when compared to pions and D mesons, while converging into a species-independent curve at higher p

_{T}

. At low and intermediate p

_{T}

, the results could be interpreted in terms of a later thermalization of charm quarks compared to light quarks, while at high p

_{T}

, path-length dependent effects seem to dominate. The J/ψ v

_{2}

measurements are further compared to a microscopic transport model calculation. Using a simplified extension of the quark scaling approach involving both light and charm quark flow components, it is shown that the D-meson v

_{n}

measurements can be described based on those for charged pions and J/ψ flow.[graphic not available: see fulltext]
