The centrality dependence of transverse momentum distributions and yields for $\\pi^{\\pm}$, $K^{\\pm}$, p and $\\bar p$ in Au+Au collisions at $\\sqrt{s_{NN}}$ = 200 GeV at mid-rapidity are measured by the PHENIX experiment at RHIC. We observe a clear particle mass dependence of the shapes of transverse momentum spectra in central collisions below ~ 2 GeV/c in $p_{T}$. Both mean transverse momenta and particle yields per participant pair increase from peripheral to mid-central and saturate at the most central collisions for all particle species. We also measure particle ratios of $\\pi^{-}$/$\\pi^{+}$, $K^{-}$/$K^{+}$, $\\bar p$/p, K/$\\pi$, p/$\\pi$ and $\\bar p$/$\\pi$ as a function of $p_{T}$ and collision centrality. The ratios of equal mass particle yields are independent of $p_{T}$ and centrality within the experimental uncertainties. In central collisions at intermediate transverse momenta 1.5-4.5 GeV/c, proton and anti-proton yields constitute a significant fraction of the charged hadron production and show a scaling behavior different from that of pions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.106657.v1/t1","@type":"Dataset","description":"Centrality dependence of the $p_{T}$ distribution for $\\pi^{+}$ in Au+Au collisions at $\\sqrt{s_{NN}}$ = 200 GeV.
