Approaches to QGP Detection (I): - Global observables -
Info: ? Evidence of production of collectively behaving strongly interacting matter: fireball volume, energy/particle density, number of colliding nucleons, lifetime, thermalization ...
1. Particle density: dN/dy
2. Energy density: dET/dy
2. Pressure/rescattering: Elliptic (and radial) collective Flow
Anisotropy in coord. space (non-central collisions) ? azim. asymmetry in mom. space in the transv. plane
Collective flow ? hydrodynamics (EoS)
