重离子碰撞的首次fm/c

The First fm/c of Heavy-Ion Collisions

Soeren Schlichting, Derek Teaney

摘要:

本文介绍了高能重离子碰撞的早期动力学和高温QCD动力学。夸克-胶子等离子体中的平衡机制反映了多体系统的非阿贝尔性和超相对论性。从一个简短的暴露的关键理论和实验问题,我们提供了一个概述的理论工具,在弱耦合研究的早期非平衡动力学。我们强调在弱耦合非阿贝尔等离子体中理解不同热化机制的理论进展,并讨论它们在描述局部热平衡的方法在第一个${\rm fm}/c$的重离子碰撞的相关性。对与重离子碰撞现象学的一些重要联系也作了简要的讨论。

英文摘要:

We present an introductory review of the early time dynamics of high-energy heavy-ion collisions and the kinetics of high temperature QCD. The equilibration mechanisms in the quark-gluon plasma uniquely reflect the non-abelian and ultra-relativistic character of the many body system. Starting with a brief expose of the key theoretical and experimental questions, we provide an overview of the theoretical tools employed in weak coupling studies of the early time non-equilibrium dynamics. We highlight theoretical progress in understanding different thermalization mechanisms in weakly coupled non-abelian plasmas, and discuss their relevance in describing the approach to local thermal equilibrium during the first ${\rm fm}/c$ of a heavy-ion collision. Some important connections to the phenomenology of heavy-ion collisions are also briefly discussed.
