"QGP" effects: pQCD calculations vs. data
LO pQCD calculations including: kT enhancement, nuclear PDFs & modified FFs to take into account medium-induced energy loss.
- Peripheral collisions well described with L/l ~1.-1.5 (GLV), dE/dx ~ 0. (X.N.W.)
- Suppression at pT>1.5 GeV/c in central collisions described with L/l ~3.-4. , dE/dx=0.25 GeV/fm (expanding source) º dE/dx|eff ~ 7 GeV/fm (static source)
First hint of final-state medium effect (fast parton energy loss in QGP) ?
