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

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

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

  • (consistent with observed larger RAA for h± than for p0 in the same pT range).
  • Different production mechanisms for baryons and mesons in the intermediate pT range ...
