High pT suppression - Particle dependence (III): p/π, h±/π

Central colls.: p/π ~ 0.8 (at pT = 2 - 4 GeV/c) at variance with perturbative production mechanisms (favour lightest meson).
Periph. colls.: p/π ~ 0.2 as in p+p,p (ISR,FNAL) & in e+e- jet fragmentation
Baryon enhancement limited to pT < 4.5 GeV/c: Charged hadron (h± = π± + p(pbar) + K± ) and π0 equally suppressed above pT ~ 5 GeV/c:
h / π ~ 1.6 as in p+p (perturbative ratio)

Central colls.: p/π ~ 0.8 (at pT = 2 - 4 GeV/c) at variance with perturbative production mechanisms (favour lightest meson).
