从相对论性核-核碰撞反应区我们能学到什么?

What Can We Learn from Reaction Zone in Relativistic Nucleus-Nucleus Collisions?

D. Anchishkin, A. Muskeyev, S. Yezhov

摘要:

我们应用“反应区”作为研究相对论性核碰撞形成的相互作用系统的工具。利用粒子碰撞强度(单位时间内单位体积内粒子碰撞的次数)研究了火球的时空结构。在这种方法中,系统演化的三个基本区域由碰撞强度的尺度分开:热火球区,冷火球区和剩余相互作用区。结果表明,反应区的概念可用于确定化学冻结和急剧的动力学冻结的超曲面。

英文摘要:

We apply the ``zone of reactions'' as a tool in studying the interacting system formed in a collision of relativistic nuclei. With the use of the intensity of collisions of particles (the number of collisions in unit volume per unit time), we study the space-time structure of a fireball. In this approach, three basic regions for the evolution of a system are separated by the scale of the intensity of collisions: the zone of a hot fireball, the zone of a cold fireball, and the zone of residual interaction. It is shown that the conception of a zone of reactions can be used for the determination of the hypersurfaces of a chemical freeze-out and a sharp kinetic freeze-out.
