Abstract (data abstract)
'Transverse momentum spectra of $\pi^{\pm}$, p and $\bar{p}$ up to 12 GeV/c at mid-rapidity in centrality selected Au+Au collisions at $\sqrt{s}_{NN}$ = 200 GeV are presented. In central Au+Au collisions, both $\pi^{\pm}$ and p($\bar{p}$) show significant suppression with respect to binary scaling at $p_{T}$ $\gtrsim$ 4GeV/c. Protons and anti-protons are less suppressed that $\pi^{\pm}$, in the range 1.5 $\lesssim$ $p_{T}$ $\lesssim$ 6 GeV/c. The $\pi^{-}$/$\pi^{+}$ and $\bar{p}$/p ratios show at most a weak $p_{T}$ dependence and no significant centrality dependence. The p/$\pi$ ratios in central Au+Au collisions approach the values in p+p and d+Au collisions at $p_{T}$ $\gtrsim$ 5 GeV/c. The results at high at $p_{T}$ indicate that the partonic sources of $\pi^{\pm}$, p and $\bar{p}$ have similar energy loss when traversing the nuclear medium.'
