P. Braunmunzinger et J. Stachel, PROBING THE PHASE-BOUNDARY BETWEEN HADRONIC MATTER AND THE QUARK-GLUON PLASMA IN RELATIVISTIC HEAVY-ION COLLISIONS, Nuclear physics. A, 606(1-2), 1996, pp. 320-328
We discuss recent data on particle production with emphasis on the deg
ree of thermal and chemical equilibration achieved. The data are inter
preted in terms of a resonance gas model. The phase boundary construct
ed between the resonance gas and the quark-gluon plasma is shown to be
very close to the deduced parameters characterizing the hadronic fire
ball at freeze-out.
