夸克-胶子等离子体的流体力学流动和规范/引力对应

Hydrodynamic Flow of the Quark-Gluon Plasma and Gauge/Gravity Correspondence

Michal P. Heller, Romuald A. Janik, R. Peschanski

摘要:

本文综述了规范/引力方法在研究重离子碰撞中形成的夸克-胶子等离子体的流体力学流动中的应用。考虑到超对称Yang-Mills理论的理想情形,AdS/CFT对应给出了规范/引力对偶的精确形式,强耦合膨胀等离子体的性质与5维黑洞在第5维中运动的度规一一对应,其变形符合相关的爱因斯坦方程.最近研究的几个方面,这一框架的回顾和透视。本文是作者就这一主题所作的四次演讲的书面版本。

英文摘要:

The contribution presents a summary of the Gauge/Gravity approach to the study of hydrodynamic flow of the quark-gluon plasma formed in heavy-ion collisions. Considering the ideal case of a supersymmetric Yang-Mills theory for which the AdS/CFT correspondence gives a precise form of the Gauge/Gravity duality, the properties of the strongly coupled expanding plasma are put in one-to-one correspondence with the metric of a 5-dimensional black hole moving away in the 5th dimension and its deformations consistent with the relevant Einstein equations. Several recently studied aspects of this framework are recalled and put in perspective. This paper is a written version of the four lectures given by the authors on that subject.
