Approaches to QGP Detection (foreword): -Comparing to what ? Baseline pp & pA observables -

• Observing formation of a hot hadronic medium requires comparing to:

  • No medium : p+p data [scaled by number of collisions/participants]
  • Cold medium : p+A data [scaled by number of collisions/participants]

• Determining Ncolls & Npart: Glauber geometrical model (nucleon mean free path, inelastic cross-section, nucleon distributions, eikonalization)
