Hadron composition at high-pT (1): RAA (p,pbar)

• Protons (antiprotons) NOT suppressed in central Au+Au (pT < 4.5 GeV/c)

• Ratio central/periph ~ RAA  1 . (Ncoll scaling holds for baryons).

  • (Consistent with observed RAA(h±) > RAA(p0) in the same pT range).
  • Points to different production mechanisms for baryons and mesons in the intermediate pT range ...
