The first measurement of the $\\Upsilon(1{\\rm S})$ elliptic flow coefficient ($v_2$) is performed at forward rapidity (2.5 < $y$ < 4) in Pb--Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV with the ALICE detector at the LHC. The results are obtained with the scalar product method and are reported as a function of transverse momentum ($p_{\\rm T}$) up to 15 GeV/$c$ in the 5--60\\% centrality interval. The measured $\\Upsilon(1{\\rm S})$ $v_2$ is consistent with zero and with the small positive values predicted by transport models within uncertainties. The $v_2$ coefficient in 2 < $p_{\\rm T}$ < 15 GeV/$c$ is lower than that of inclusive J/$\\psi$~mesons in the same $p_{\\rm T}$ interval by 2.6 standard deviations. These results, combined with earlier suppression measurements, are in agreement with a scenario in which the $\\Upsilon$(1S) production in Pb--Pb collisions at LHC energies is dominated by dissociation limited to the early stage of the collision whereas in the J/$\\psi$ case an additional regeneration component is possibly present.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.91161.v1/t1","@type":"Dataset","description":"The J/$\\psi$ $v_2$ coefficient as a function of $p_{\\rm T}$ in 5-60% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.91161.v1/t2","@type":"Dataset","description":"The $\\Upsilon$(1S) $v_2$ coefficient as a function of $p_{\\rm T}$ in 5-60% centrality interval in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.91161.v1/t3","@type":"Dataset","description":"The J/$\\psi$ $v_2$ coefficient in three centrality intervals integrated over the transverse momentum range 2~$<$~$p_{\\rm T}$~$<$~15 GeV/$c$ in Pb-Pb collisions...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.91161.v1/t4","@type":"Dataset","description":"The $\\Upsilon$(1S) $v_2$ coefficient in three centrality intervals integrated over the transverse momentum range 2~$<$~$p_{\\rm T}$~$<$~15 GeV/$c$ in Pb-Pb collisions...","name":"Table 4"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1742764?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/91161"}],"inLanguage":"en","name":"Measurement of $\\Upsilon(1{\\rm S})$ elliptic flow at forward rapidity in Pb-Pb collisions at $\\sqrt{s_{\\rm{NN}}}=5.02$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1742764?version=1","version":1}
