This measurement is compared to that of pions, kaons, and protons at the same center-of-mass energy. A clear mass ordering is observed at low $p_{\\rm{T}}$, as expected from relativistic hydrodynamics. The violation of the scaling of $v_{2}$ with the number of constituent quarks at low $p_{\\rm{T}}$, already observed for identified hadrons and deuterons at LHC energies, is confirmed also for (anti-)$^{3}$He. The elliptic flow of (anti-)$^{3}$He is underestimated by the Blast-Wave model and overestimated by a simple coalescence approach based on nucleon scaling. The elliptic flow of (anti-)$^{3}$He measured in the centrality classes 0-20% and 20-40% is well described by a more sophisticated coalescence model where the phase-space distributions of protons and neutrons are generated using the iEBE-VISHNU hybrid model with AMPT initial conditions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.95240.v1/t1","@type":"Dataset","description":"Event-plane resolution $R_{\\Psi_{2}}$ of the second harmonic as a function of the collision centrality.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.95240.v1/t2","@type":"Dataset","description":"Elliptic flow ($v_{2}$) of (anti-)$^{3}$He measured in Pb-Pb collisions at \\sqrt{s_{\\mathrm{NN}}} = 5.02 TeV for the centrality classes 0--20$\\%$, 20--40$\\%$,...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.95240.v1/t3","@type":"Dataset","description":"Elliptic flow ($v_{2}$) of (anti-)$^{3}$He measured in Pb-Pb collisions at \\sqrt{s_{\\mathrm{NN}}} = 5.02 TeV for the centrality classes 0--20$\\%$, 20--40$\\%$,...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.95240.v1/t4","@type":"Dataset","description":"Elliptic flow ($v_{2}$) of (anti-)$^{3}$He measured in Pb-Pb collisions at \\sqrt{s_{\\mathrm{NN}}} = 5.02 TeV for the centrality classes 0--20$\\%$, 20--40$\\%$,...","name":"Table 4"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1760170?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/95240"}],"inLanguage":"en","name":"Measurement of the (anti-)$^{3}$He elliptic flow 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/ins1760170?version=1","version":1}
