Summary

 High pT central Au+Au vs p+p at midrapidity at RHIC:
(1) Inclusive spectra suppressed by a factor of 4-5 at 200 GeV and by a factor of ~3 at 62.4 GeV

(2): Intermediate pT hadron composition inconsistent with known fragmentation functions in free space.

(3) Disappearance of away-side jet correlations. Enhanced mono-jet pattern following line of longest path.

 High pT d+Au vs p+p at midrapidity at RHIC:

(4) Spectra enhanced by a factor ~1.3

“Explanation” (1,2 via 4): pQCD hard scattering + final-state parton energy loss + quark recombination in dense thermal QCD medium.

QGP ? : thermal γ ?, J/Ψ suppression ? (Run-4 AuAU @ 200 GeV)

 High pT in d+Au at forward rapidities at RHIC:

(5) Spectra suppressed by a factor ~2.

“Explanation” : possible evidence of higher twist effects at small-x.
