Summary (I)
Vast amount of high pT data (dN/dpT, dN/dφ for h±,π0,K0s,p,p,Λ,Λ, diff. centrality classes...) in Au+Au, d+Au, and p+p collisions @ √s = 200 GeV
Central Au+Au collisions :
- Strong suppression (factor ~ 4-5) of all hadrons (with respect to Ncoll scaling) above pT~ 5 GeV/c.
- Flat and universal (pid-wise) pT dependence of suppression >5 GeV/c.
- Very different behaviour than at lower √s (“Cronin” enhancement).
- Smooth centrality dependence of suppression (weak Npart scaling).
- No apparent suppression of baryons in pT~2-5 GeV/c: “anomalous” p/p ~ 0.8 ratio >> p/p ~ 0.2 in p+p and e+e- jet fragmentation.
- Strong elliptic flow signal (early collective rescattering).
- Jet-like signal in near-side azimuthal correlations.
- Disappearance of jet away-side azimuthal correlations.
