Intermediate pT mesons suppressed. Baryons are not

• Strongly enhanced baryon (p, L) production at pT ~ 2 – 4 GeV/c

• Strong centrality dependent baryon/meson: ratio well above “perturbative” (pp) ratios.

• Clear deviation from std. vacuum fragmentation functions (large non-pQCD effects) calls for extra baryon production mechanism: recombination.

• Above pT ~ 6 GeV/c: Recovery of “vacuum” fragmentation ratio. Baryons suppressed too.
