Hadron composition at high-pT (I): 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).
  • Indicates different production mechanisms for baryons and mesons in the intermediate pT range.
