The second ($v_2$) and third ($v_3$) flow harmonic coefficients of J/$\\psi$ mesons are measured at forward rapidity (2.5 $<$ $y$ $<$ 4.0) in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$ = 5.02 TeV with the ALICE detector at the LHC. Results are obtained with the scalar product method and reported as a function of transverse momentum, $p_{\\rm T}$, for various collision centralities. A positive value of J/$\\psi$ $v_3$ is observed with 3.7$\\sigma$ significance. The measurements, compared to those of prompt D$^0$ mesons and charged particles at mid-rapidity, indicate an ordering with $v_{\\rm n}$(J/$\\psi$) $<v_{\\rm n}$(D$^0$) $<v_{\\rm n}$(h$^\\pm$) (n = 2, 3) at low and intermediate $p_{\\rm T}$ up to 6 GeV/$c$ and a convergence with $v_2$(J/$\\psi$) $\\approx v_2$(D$^0$) $\\approx v_2$(h$^\\pm$) at high $p_{\\rm T}$ above 6-8 GeV/$c$. In semi-central collisions (5-40% and 10-50% centrality intervals) at intermediate $p_{\\rm T}$ between 2 and 6 GeV/$c$, the ratio $v_3/v_2$ of J/$\\psi$ mesons is found to be significantly lower (4.6$\\sigma$) with respect to that of charged particles. In addition, the comparison to the prompt D$^0$-meson ratio in the same $p_{\\rm T}$ interval suggests an ordering similar to that of the $v_2$ and $v_3$ coefficients. The J/$\\psi$ $v_2$ coefficient is further studied using the Event Shape Engineering technique. The obtained results are found to be compatible with the expected variations of the eccentricity of the initial-state geometry.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t1","@type":"Dataset","description":"The J/$\\psi$ $v_2$ coefficient as a function of $p_{\\rm T}$ in 0-10% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t2","@type":"Dataset","description":"The J/$\\psi$ $v_2$ coefficient as a function of $p_{\\rm T}$ in 10-30% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t3","@type":"Dataset","description":"The J/$\\psi$ $v_2$ coefficient as a function of $p_{\\rm T}$ in 30-50% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t4","@type":"Dataset","description":"The J/$\\psi$ $v_3$ coefficient as a function of $p_{\\rm T}$ in 0-10% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t5","@type":"Dataset","description":"The J/$\\psi$ $v_3$ coefficient as a function of $p_{\\rm T}$ in 10-30% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t6","@type":"Dataset","description":"The J/$\\psi$ $v_3$ coefficient as a function of $p_{\\rm T}$ in 30-50% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t7","@type":"Dataset","description":"The J/$\\psi$ $v_3$ coefficient as a function of $p_{\\rm T}$ in 0-50% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t8","@type":"Dataset","description":"The J/$\\psi$ $v_3/v_2$ ratio as a function of $p_{\\rm T}$ in 5-40% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t9","@type":"Dataset","description":"The J/$\\psi$ $v_3/v_2$ ratio as a function of $p_{\\rm T}$ in 10-50% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t10","@type":"Dataset","description":"The J/$\\psi$ $v_2$ as a function of $p_{\\rm T}$ for unbiased events (no event-shape selection) in the 5-40% centrality interval...","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t11","@type":"Dataset","description":"The J/$\\psi$ $v_2$ as a function of $p_{\\rm T}$ for lowest $q_2^{\\rm V0A}$ event-shape class in the 5-40% centrality interval...","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.88308.v1/t12","@type":"Dataset","description":"The J/$\\psi$ $v_2$ as a function of $p_{\\rm T}$ for highest $q_2^{\\rm V0A}$ event-shape class in the 5-40% centrality interval...","name":"Table 12"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1706006?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/88308"}],"inLanguage":"en","name":"Study of J/$\\psi$ azimuthal anisotropy at forward rapidity in Pb-Pb collisions at $\\sqrt{{\\textit s}_{\\rm NN}}$ = 5.02 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1706006?version=1","version":1}
