Final-state QGP effects
Multiple final-state gluon radiation off the produced
hard parton induced by the traversed dense
colored medium:
- Mean parton energy loss probes medium
- properties:
- DE ~ gluon (gluon density)
- DE ~ DL2 (medium length)
-
- Energy is carried away by gluon-sstrahung
- outside jet cone: dE/dx ~ s k2T
- Formalisms: BDMPS (thick plasma), GLV (thin plasma),
- Wiedemann&Salgado (combined).
- Correction for expanding plasma (1-D):
- E1-D =(20/RA) · Estat ~ 15·Estat (0=0.2 fm/c, RA=6 fm)
Suppression of inclusive high pT leading hadrons due to final-state radiation.
