Dielectron spectrum in relativistic HI collisions

• Francois Gelis' yesterday question:

• "What exp. range in Minv and pT for HTL virtual photons are you interested in?"

• Lepton and lepton pairs are “clean” probes of early stage of heavy ion collision:

• r, w, f in dense matter 0 Chiral symmetry restoration

• D,B 0 Heavy quarks energy loss

• J/Y production 0Deconfinement

• Thermal dielectron continuum 0 Direct radiation from QGP

  • á Intermediate & high mass (Minv >1 GeV/c2) ; pT> 0.5 GeV/c ?
  • Let's see what the first dielectron results from RHIC tell us ...
