In minimum bias Au+Au collisions at sqrt(s_NN) = 200 GeV, a significant amount of elliptic flow, comparable to other non-strange baryons, is observed for multi-strange baryons which are expected to be particularly sensitive to the dynamics of the partonic stage of heavy-ion collisions. The $p_T$ dependence of $v_2$ of the multi-strange baryons confirms the number of constituent quark scaling previously observed for lighter hadrons. These results support the idea that a substantial fraction of the observed collective motion is developed at the early partonic stage in ultra-relativistic nuclear collisions at RHIC.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.102945.v1/t1","@type":"Dataset","description":"$\\Xi^{-} + \\Xi^{+}$ invariant mass distribution from minimum bias (0\u201380%) Au + Au collisions at $\\sqrt{s_{NN}}$ = 200 GeV.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.102945.v1/t2","@type":"Dataset","description":"$\\Omega^{-} + \\Omega^{+}$ invariant mass distribution from minimum bias (0\u201380%) Au + Au collisions at $\\sqrt{s_{NN}}$ = 200 GeV.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.102945.v1/t3","@type":"Dataset","description":"Azimuthal distributions with respect to the event plane of the $\\Xi^{-} + \\Xi^{+}$ and $\\Omega^{-} + \\Omega^{+}$ raw yields.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.102945.v1/t4","@type":"Dataset","description":"$v_2(p_T)$ of $\\Xi^{-} + \\Xi^{+}$ and $\\Omega^{-} + \\Omega^{+}$ from 200 GeV Au+Au minimum bias collisions.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.102945.v1/t5","@type":"Dataset","description":"Number of quark ($n_q$) scaled $v_2$ as a function of scaled $p_T$ for $\\Xi^{-} + \\Xi^{+}$ and $\\Omega^{-} + \\Omega^{+}$...","name":"Table 5"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins681161?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/102945"}],"inLanguage":"en","name":"Multi-strange baryon elliptic flow in Au + Au collisions at s(NN)**(1/2) = 200-GeV.","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins681161?version=1","version":1}
