Sažetak
Transverse momentum spectra of π±, p, and p⎯⎯ up to 12 GeV/c at midrapidity in centrality selected Au+Au collisions at sNN‾‾‾‾√=200 GeV are presented. In central Au+Au collisions, both π± and p(p⎯⎯) show significant suppression with respect to binary scaling at pT≳4 GeV/c. Protons and antiprotons are less suppressed than π±, in the range 1.5≲pT≲6 GeV/c. The π−/π+ and p⎯⎯/p ratios show at most a weak pT dependence and no significant centrality dependence. The p/π ratios in central Au+Au collisions approach the values in p+p and d+Au collisions at pT≳5 GeV/c. The results at high pT indicate that the partonic sources of π±, p, and p⎯⎯ have similar energy loss when traversing the nuclear medium.
