Hard probes & single electron continuum [PRL 88, 192303 (2002)]

• Hard probes signals contributing to electron spectrum:

  • Heavy quark: open charm & bottom (via semi-leptonic decays c  eX, b eX): Initial gluon density, energy loss of heavy flavors, baseline for J/ suppression ...
  • Thermal dileptons, direct photons (virtual, conversion), Drell-Yan.

• Background "cocktail":
