Approaches to QGP Detection (II): -Large cross-section probes -

• 4. Space-time size of source at freeze-out:

• Freeeze-out geometry, expansion dynamics

• HBT Correlations of boson pairs:

  • Þ p± p± , K±K± , g g , p0p0
  • 5. Baryo-chemical potential and temperature at freeze-out:
  • Particles ratios
  • Þ hadrons

• 6. Others ...

• Critical phenomena associated to phase transition:

• Event-by-event fluctuations (in <pT>, particles ratios…)

• Disoriented Chiral Condensates (DCC’s)entauro evts.)

  • Photons (from p0), charged hadrons

• Strangelets …
