Centrality dependence of p0 suppression

• Suppression vs Npart:

• Smooth suppression (no 1st order phase transition-like behavior).

• RAA < 1 for 50-70% centrality: Npart ~ 40 ± 15 (coincidental agreement with parton percolation predictions ?)

• Suppression vs ET:

• ET measured in EMCal (S. Bazilevsky talk)

• Suppression apparent up to 50-60% centrality:

• ET~ 20.5 GeV
