TL;DR

This paper explores how the finite width of quark-gluon plasma (QGP) bags affects their equation of state and proposes a method to distinguish critical points through decay lifetime measurements.

Contribution

Findings

Finite width influences the QGP equation of state.

Measurement of decay lifetimes can identify critical point existence.

The model offers a new way to analyze QGP properties in high-energy collisions.

Abstract

Within an exactly solvable model I discuss an influence of the medium dependent finite width of QGP bags on their equation of state. It is shown that inclusion of such a width allows one to naturally resolve two conceptual problems of the QGP statistical description. On the basis of the proposed simple kinetic model for a sequential decay of heavy QGP bags formed in high energy elementary particle collisions it is argued that by measuring the energy dependence of life time of these bags it is possible to distinguish the case of critical point existence from the case of tricritical point.
