Summary
Jet production and fragmentation:
Good agreement of the jet properties in pp collisions with other lower s experiments
dAu jT and kT consistent with pp
In AuAu significant broadening of “effective” kT - with centrality
Back-to-back correlations
Suppression of away-side jet → jet quenching picture
Suppression dependent on reaction plane orientation
No strong flavor dependence at intermediate pT observed
Near-side correlations
Evidence for near-side jet broadening in central Au+Au
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 in d+Au at forward rapidities at RHIC:
(5) Spectra suppressed by a factor ~2.
