Summary (II)
Two most interesting physical “discoveries” @ RHIC:
- 1. High pT suppression.
- 2. High pT baryon/meson enhancement.
-
“Clear signals of strong medium effects at work !”
What do we learn about the medium properties ? QGP yes/no ?
Final-state partonic jet quenching ? (QGP)
Initial-state saturation of nuclear wave functions ? (CGC)
Final-state hadronic absorption ? (very dense hadron medium)
other ... ?
Answers:
- Experimental: d+Au ...
- Theoretical: Does scenario “X” consistently explains: the magnitude, pT dependence, centrality evolution, and flavor behaviour of RHIC high-pT suppression ?
