The fact: “ High-pT hadron suppression observed at RHIC @ √sNN= 130 GeV”

Clear hint of medium effects at work ! (especially p0)
Initial-state nuclear ? final-state hadronic ? final-state partonic ?
The goal: “ Let's see what happens at higher energy (200 GeV), with much higher statistics, for much larger pT values, and for finer centrality classes
