P° Production at high pT in central Au+Au and p+p collisions at √sNN = 200 GeV in STAR

The p° production at high p T (5.0 ≤ p T ≤ 10.0 GeV/c) measured in minimum bias p+p, Au+Au and central Au+Au collisions in the STAR detector is presented. The p 0 /π ratio measured in p+p is compared to PYTHIA calculations as a test of perturbative quantum chromodynamics (pQCD) that describes reasonably well particle production from hard processes. The p° nuclear modification factor is also presented. In p+p collisions, charged pions and (anti-)protons are measured in the range 5.0 ≤ p T ≤ 15.0 GeV/c, and the anti-particle to particle ratio and the baryon-to-meson ratios of these hadrons are discussed.
