We report a precise measurement of the J/$\\psi$ elliptic flow in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}=5.02$ TeV with the ALICE detector at the LHC. The J/$\\psi$ mesons are reconstructed at mid-rapidity ($|y| < 0.9$) in the dielectron decay channel and at forward rapidity ($2.5<y<4.0$) in the dimuon channel, both down to zero transverse momentum. At forward rapidity, the elliptic flow $v_2$ of the J/$\\psi$ is studied as a function of transverse momentum and centrality. A positive $v_2$ is observed in the transverse momentum range $2 < p_{\\rm T} < 8$ GeV/$c$ in the three centrality classes studied and confirms with higher statistics our earlier results at $\\sqrt{s_{\\rm NN}} = 2.76$ TeV in semi-central collisions. At mid-rapidity, the J/$\\psi$ $v_2$ is investigated as a function of transverse momentum in semi-central collisions and found to be in agreement with the measurements at forward rapidity. These results are compared to transport model calculations. The comparison supports the idea that at low $p_{\\rm T}$ the elliptic flow of the J/$\\psi$ originates from the thermalization of charm quarks in the deconfined medium, but suggests that additional mechanisms might be missing in the models.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.80235.v1/t1","@type":"Dataset","description":"Transverse momentum dependence of inclusive J/$\\psi$ $v_2$ at $\\sqrt{s_{\\rm NN}}=5.02$ TeV for the 20-40% centrality class (forward rapidity).
