We report transverse momentum ($p_T \\leq 15$ GeV/c) spectra of $\\pi^{\\pm}$, $K^{\\pm}$ and $p$, $\\bar{p}$, $K^0_S$, and $\\rho^0$ at mid-rapidity in p+p and Au+Au collisions at $\\sqrt{s_{NN}} = 200$ GeV. Perturbative QCD calculations are consistent with $\\pi^{\\pm}$ spectra in p+p collisions but do not reproduce $K$ and $p$($\\bar{p}$) spectra. The observed decreasing antiparticle-to-particle ratios with increasing $p_T$ provide experimental evidence for varying quark and gluon jet contributions to high-$p_T$ hadron yields. The relative hadron abundances in Au+Au at $p_T > 8$ GeV/c are measured to be similar to the p+p results, despite the expected Casimir effect for parton energy loss.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.95749.v1/t1","@type":"Dataset","description":"The invariant yields $d^2N/(2\\pi p_T dp_T dy)$ of $\\pi^{\\pm}$, $K^{\\pm}$, $p$, and $\\bar{p}$ from non-singly diffractive p+p collisions ($\\sigma_{NSD} =...","name":"Figure 1.1: Invariant yield vs $p_T$ in p+p collisions."},{"@id":"https://doi.org/10.17182/hepdata.95749.v1/t2","@type":"Dataset","description":"The invariant yields $d^2N/(2\\pi p_T dp_T dy)$ of $K^0_S$ from non-singly diffractive p+p collisions ($\\sigma_{NSD} = 30.0 \\pm 3.5$ mb),...","name":"Figure 1.2: Invariant yield vs $p_T$ in p+p collisions."},{"@id":"https://doi.org/10.17182/hepdata.95749.v1/t3","@type":"Dataset","description":"The invariant yields $d^2N/(2\\pi p_T dp_T dy)$ of $\\rho^0$ from non-singly diffractive p+p collisions ($\\sigma_{NSD} = 30.0 \\pm 3.5$ mb),...","name":"Figure 1.3: Invariant yield vs $p_T$ in p+p collisions."},{"@id":"https://doi.org/10.17182/hepdata.95749.v1/t4","@type":"Dataset","description":"The invariant yields $d^2N/(2\\pi p_T dp_T dy)$ of $K + p(\\bar{p})$ in central Au+Au collisions, and NLO calculations with AKK...","name":"Figure 1.4: Invariant yield vs $p_T$ in Au+Au (0-12%) collisions"},{"@id":"https://doi.org/10.17182/hepdata.95749.v1/t5","@type":"Dataset","description":"The invariant yields $d^2N/(2\\pi p_T dp_T dy)$ of $\\rho^0$ in central Au+Au collisions, and NLO calculations with AKK [9] and...","name":"Figure 1.5: Invariant yield vs $p_T$ in Au+Au (0-12%) collisions"},{"@id":"https://doi.org/10.17182/hepdata.95749.v1/t6","@type":"Dataset","description":"The invariant yields $d^2N/(2\\pi p_T dp_T dy)$ of $K^0_S$ in central Au+Au collisions, and NLO calculations with AKK [9] and...","name":"Figure 1.6: Invariant yield vs $p_T$ in Au+Au (0-12%) collisions"},{"@id":"https://doi.org/10.17182/hepdata.95749.v1/t7","@type":"Dataset","description":"Yield ratios $\\pi^\u2212/\\pi^+$, $\\bar{p}/p$, $K^\u2212/K^+$, $p/\\pi^+$, $\\bar{p}/\\pi^\u2212$, and $K^{\\pm}/\\pi^{\\pm}$ versus $p_T$ in p+p collisions, and nominal NLO calculations with AKK...","name":"Figure 2.1: Particle ratios vs $p_T$ in p+p collisions."},{"@id":"https://doi.org/10.17182/hepdata.95749.v1/t8","@type":"Dataset","description":"Yield ratio $K^0_S$)/$\\pi^{\\pm}$ versus $p_T$ in p+p collisions, and nominal NLO calculations with AKK [9] and DSS [10] FFs without...","name":"Figure 2.2: Particle ratios vs $p_T$ in p+p collisions."},{"@id":"https://doi.org/10.17182/hepdata.95749.v1/t9","@type":"Dataset","description":"Yield ratios $p/\\pi^+$ and $\\bar{p}/\\pi^\u2212$ versus $p_T$ in central Au+Au collisions [14] with updated uncertainties at high $p_T$.
