- Small cross-section (penetrating) probes -
1. Colour screening (deconfinement):
Debye-screening in QGP
Quarkonia suppression: J/Y, ?
- Electrons pairs, Muons pairs
2. Thermal radiation from QGP:
Real and virtual photons convey undistorted info on
the thermodyn. state (T) of the medium (? EoS)
Direct g, Direct g* (e+e-, m+m - )
- Direct photons, Electrons pairs, Muons pairs
3. Dense QGP (Jet Quenching):
Hard-scattering particles suffer a huge energy loss
inside the plasma (g radiation): 2 GeV/fm ~ 1 MJ/m !!
Jet suppression via high pT leading particle spectra:
- Photons (from p0), ch. hadrons, (g-tagged) jets
4. Open charm (& beauty) :
Production of D, B mesons:
- Electrons, Muons
