重离子碰撞中的动力学平衡:弹性过程的作用

Kinetic equilibration in heavy ion collisions: the role of elastic processes

Julien Serreau

摘要:

讨论了高能重离子碰撞早期的热化问题。我们回顾了最近的一项研究,我们明确地表明,相反,一个广泛使用的假设,产生的部分子之间的弹性碰撞是不足以迅速驱动系统向局部动力学平衡。然后,我们简要地讨论了最近的事态发展有关的动力学平衡的描述和评论有关的现象学的一些开放的问题。

英文摘要:

We discuss the question of thermalization during the very early stages of a high energy heavy ion collision. We review a recent study where we explicitely showed that, contrarily to a widely used assumption, elastic collisions between the produced partons are not sufficient to rapidly drive the system toward local kinetic equilibrium. We then briefly discuss recent developments concerning the description of kinetic equilibration and comment on some open issues related to phenomenology.
