关于夸克-胶子等离子体袋的有限宽度

On Finite Width of Quark Gluon Plasma Bags

K. A. Bugaev

摘要:

在一个精确可解的模型中,讨论了介质依赖的有限宽度QGP袋对状态方程的影响。结果表明,包括这样的宽度允许一个自然地解决两个概念问题的QGP统计描述。基于所提出的高能基本粒子碰撞中形成的重QGP袋的连续衰变的简单动力学模型,认为通过测量这些袋的寿命与能量的关系,可以区分临界点存在的情况和三临界点的情况。

英文摘要:

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.
