Up–tp 94/1 Time-like Shock Hadronization of a Supercooled Quark-gluon Plasma
نویسنده
چکیده
We study the energy-momentum and baryonic number conservation laws for quark-gluon plasma discontinuity transitions into hadron matter states. We find that the time-like shock hadronization of a supercooled quark-gluon plasma (when the normal vector to the discontinuity hypersurface is timelike) should take place. We consider some properties of this process, which is different from the standard space-like shock hadronization. Permanent address: Institute for Theoretical Physics, 252143 Kiev-143, Ukraine

Statistical hadronization of supercooled quark-gluon plasma
The fast simultaneous hadronization and chemical freeze-out of supercooled quark-gluon plasma, created in relativistic heavy ion collisions, can lead to the reheating of the expanding matter and to the change in a collective flow profile. We use the assumption of statistical nature of the hadronization process, and study quantitatively the freeze-out in the framework of hydrodynamical Bjorken m...

We reexamine the scenario of homogeneous nucleation of the quark-gluon plasma produced in ultra-relativistic heavy ion collisions. A generalization of the standard nucleation theory to rapidly expanding system is proposed. The nucleation rate is derived via the new scaling parameter λZ . It is shown that the size distribution of hadronic clusters plays an important role in the dynamics of the p...

The general formalism of homogeneous nucleation theory is applied to study the hadronization pattern of the ultra-relativistic quark-gluon plasma (QGP) undergoing a first order phase transition. A coalescence model is proposed to describe the evolution dynamics of hadronic clusters produced in the nucleation process. The size distribution of the nucleated clusters is important for the descripti...
متن کاملChallenges and Successes
Highly effective conversion of kinetic energy into abundant particle multiplicity is the remarkable feature discovered in high energy heavy ion collisions. This short and pedagogic review addresses topical issues related to the understanding of this phenomenon, originating in the creation of the deconfined quark–gluon plasma phase. I consider in depth the apparently simple, yet sometimes misund...
