Summary (II)
PHENIX global results :
Very high energy density (~70% larger than at SPS) well above the expected critical value for QGP.
Large particle production, rising faster than number of participant nucleons (onset of hard processes, saturation physics ?).
Much closer to baryon-free central region than at SPS.
PHENIX high-pT results :
High-pT charged hadron and 0 spectra central collisions: factor 3-- 6 suppression (qualitative agreement with energy loss in opaque medium).
Increased baryon over meson yield above pT ~ 2 GeV/c (very different from pp data). p,pbar not suppressed.
Strong elliptic flow signal (early collective rescattering).
Jet-like signal in azimuthal near-side correlations.
PHENIX heavy-flavor results :
Single electron spectrum/cross-section consistent with pp scaled open charm production (no apparent medium effect).
First results on charmonium.
Run-3: d+Au collisions @ sNN = 200 GeV “cold nuclear medium” reference: role of initial-state effects (no significant final-state effs. expected)
