PHASE-TRANSITION DYNAMICS IN QGP HADRONIZATION

Our aim is to study quantatively the process of QGP cooling and hadron ization. Following the statistical theory of the first order phase tra nsitions we have to operate with such categories as nucleation rate, p re-exponential factor, surface free energy of bubbles and velocity of bubble growth. We compute the temperature, average bubble size, bubble density and fraction of space converted to the hadronic phase as a fu nction of time. Also, we check the sensitivity of our scenarios to var iations of the parameters mentioned above, as well as different scheme s of QGP expansion: from longitudinal to spherical expansion. The resu lts obtained are compared to idealized adiabatic Maxwell equilibrium s cenario.
