Measurements are done in $Au + Au$ collisions at $\\sqrt{s_{NN}} = 27$ GeV and $\\sqrt{s_{NN}} = 200$ GeV. For 10-40\\% centrality, we examine quark coalescence behavior for particle combinations with identical quark content, and search for any departure from this behavior (``splitting'') for combinations having non-identical quark content. Under the assumption of quark coalescence for produced quarks, the splitting strength appears to increase with the electric charge difference of the constituent quarks in the combinations, consistent with electromagnetic effect expectations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t1","@type":"Dataset","description":"Directed flow of $\\Xi^{-}$ and $\\overline{\\Xi}^{+}$ versus rapidity for 10-40\\% Au+Au collisions at $\\sqrt{s_{\\mathrm{NN}}} = 27$ GeV.","name":"Figure 2(a)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t2","@type":"Dataset","description":"Directed flow of $\\Omega^{-}$ and $\\overline{\\Omega}^{+}$ versus rapidity for 10-40\\% Au+Au collisions at $\\sqrt{s_{\\mathrm{NN}}} = 27$ GeV.","name":"Figure 2(b)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t3","@type":"Dataset","description":"Directed flow of $\\Xi^{-}$ and $\\overline{\\Xi}^{+}$ versus rapidity for 10-40\\% Au+Au collisions at $\\sqrt{s_{\\mathrm{NN}}} = 200$ GeV.","name":"Figure 2(c)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t4","@type":"Dataset","description":"Directed flow of $\\Omega^{-}$ and $\\overline{\\Omega}^{+}$ versus rapidity for 10-40\\% Au+Au collisions at $\\sqrt{s_{\\mathrm{NN}}} = 200$ GeV.","name":"Figure 2(d)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t5","@type":"Dataset","description":"$\\Delta v_1$ versus rapidity (panel a) for ($\\Delta q,\\,\\Delta S$)=(0,~0) in 10-40\\% Au+Au at $\\sqrt{s_{\\mathrm{NN}}}=27$ GeV.","name":"Figure 3 (a)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t6","@type":"Dataset","description":"$\\Delta v_1$ versus rapidity (panel b) for ($\\Delta q,\\,\\Delta S$)=(4/3,~2) in 10-40\\% Au+Au at $\\sqrt{s_{\\mathrm{NN}}}=27$ GeV.","name":"Figure 3 (b)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t7","@type":"Dataset","description":"$\\Delta v_1$ versus $p_\\mathrm{T}/n_q$ (panel c) for ($\\Delta q,\\,\\Delta S$)=(0,~0) in 10-40\\% Au+Au at $\\sqrt{s_{\\mathrm{NN}}}=27$ GeV.","name":"Figure 3 (c)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t8","@type":"Dataset","description":"$\\Delta v_1$ versus $p_\\mathrm{T}/n_q$ (panel d) for ($\\Delta q,\\,\\Delta S$)=(4/3,~2) in 10-40\\% Au+Au at $\\sqrt{s_{\\mathrm{NN}}}=27$ GeV.","name":"Figure 3 (d)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t9","@type":"Dataset","description":"Midrapidity $\\Delta v_1$ slope versus $\\Delta q$ (a) and $\\Delta S$ (c) in 10-40\\% Au+Au at 27 GeV (a, c)....","name":"Figure 4 (a,c)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t10","@type":"Dataset","description":"Midrapidity $\\Delta v_1$ slope versus $\\Delta q$ (b) and $\\Delta S$ (d) in 10-40\\% Au+Au at 200 GeV (b, d)....","name":"Figure 4 (b,d)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t11","@type":"Dataset","description":"$\\Delta v_1$ versus rapidity (panel a) for ($\\Delta q,\\,\\Delta S$)=(0,~0) in 40-80\\% Au+Au at $\\sqrt{s_{\\mathrm{NN}}}=27$ GeV.","name":"Figure 5 (a)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t12","@type":"Dataset","description":"$\\Delta v_1$ versus rapidity (panel b) for ($\\Delta q,\\,\\Delta S$)=(4/3,~2) in 40-80\\% Au+Au at $\\sqrt{s_{\\mathrm{NN}}}=27$ GeV.","name":"Figure 5 (b)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t13","@type":"Dataset","description":"$\\Delta v_1$ versus $p_\\mathrm{T}/n_q$ (panel c) for ($\\Delta q,\\,\\Delta S$)=(0,~0) in 40-80\\% Au+Au at $\\sqrt{s_{\\mathrm{NN}}}=27$ GeV.","name":"Figure 5 (c)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t14","@type":"Dataset","description":"$\\Delta v_1$ versus $p_\\mathrm{T}/n_q$ (d) for ($\\Delta q,\\,\\Delta S$)=(4/3,~2) in 40-80\\% Au+Au at $\\sqrt{s_{\\mathrm{NN}}}=27$ GeV.","name":"Figure 5 (d)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t15","@type":"Dataset","description":"Midrapidity $\\Delta v_1$ slope versus $\\Delta q$ (a) and $\\Delta S$ (c) in 40-80\\% Au+Au at 27 GeV (a, c)....","name":"Figure 6 (a,c)"},{"@id":"https://doi.org/10.17182/hepdata.139902.v1/t16","@type":"Dataset","description":"Midrapidity $\\Delta v_1$ slope versus $\\Delta q$ (b) and $\\Delta S$ (d) in 40-80\\% Au+Au at 200 GeV (b, d)....","name":"Figure 6 (b,d)"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2649581?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/139902"}],"inLanguage":"en","name":"Electric charge and strangeness-dependent directed flow splitting of produced quarks in Au+Au collisions","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2649581?version=1","version":1}
