The yield of multi-strange baryons per participant nucleon increases from peripheral to central collisions more rapidly than the $\\Lambda$ yield, which appears to correspond to an increasing strange quark density of matter produced. The value of the strange phase space occupancy factor $\\gamma_{s}$, obtained from a thermal model fit to the data, approaches unity for the most central collisions. We also show that the nuclear modification factors, $R_{CP}$, of $\\Lambda$ and $\\Xi$ are consistent with each other and with that of protons in the transverse momentum range 2.0 < $p_{T}$ < 5.0 GeV/c. This scaling behaviour is consistent with a scenario of hadron formation from constituent quark degrees of freedom through quark recombination or coalescence.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.98928.v1/t1","@type":"Dataset","description":"Transverse momentum distributions of (a) $\\Lambda(\\overline{\\Lambda})$ for $|y|<1.0$, (b) $\\Xi^{-}(\\overline{\\Xi}^{+})$ for $|y|<0.75$ and (c) $\\Omega^{-}+\\overline{\\Omega}^{+}$ for $|y|<0.75$ in Au+Au collisions...","name":"Figure 1 a"},{"@id":"https://doi.org/10.17182/hepdata.98928.v1/t2","@type":"Dataset","description":"Transverse momentum distributions of (a) $\\Lambda(\\overline{\\Lambda})$ for $|y|<1.0$, (b) $\\Xi^{-}(\\overline{\\Xi}^{+})$ for $|y|<0.75$ and (c) $\\Omega^{-}+\\overline{\\Omega}^{+}$ for $|y|<0.75$ in Au+Au collisions...","name":"Figure 1 b"},{"@id":"https://doi.org/10.17182/hepdata.98928.v1/t3","@type":"Dataset","description":"Transverse momentum distributions of (a) $\\Lambda(\\overline{\\Lambda})$ for $|y|<1.0$, (b) $\\Xi^{-}(\\overline{\\Xi}^{+})$ for $|y|<0.75$ and (c) $\\Omega^{-}+\\overline{\\Omega}^{+}$ for $|y|<0.75$ in Au+Au collisions...","name":"Figure 1 c"},{"@id":"https://doi.org/10.17182/hepdata.98928.v1/t4","@type":"Dataset","description":"(a) The corrected integrated yield $dN/dy$ at mid-rapidity for $\\overline{\\Xi}^{+}$ , $\\overline{\\Lambda}$ and $\\overline{p}$ divided by $N_{part}$, normalized to the...","name":"Figure 2 up"},{"@id":"https://doi.org/10.17182/hepdata.98928.v1/t5","@type":"Dataset","description":"(a) The corrected integrated yield $dN/dy$ at mid-rapidity for $\\overline{\\Xi}^{+}$ , $\\overline{\\Lambda}$ and $\\overline{p}$ divided by $N_{part}$, normalized to the...","name":"Figure 2 down"},{"@id":"https://doi.org/10.17182/hepdata.98928.v1/t6","@type":"Dataset","description":"$R_{CP}$ for $\\Xi^{-}+\\overline{\\Xi}^{+}$ and $\\Omega^{-}+\\overline{\\Omega}^{+}$ at mid-rapidity (centrality interval : 0 \u2212 5% vs. 40 \u2212 60%).
