标题： High Temperature QCD

摘要： 我讨论有限温度规范理论作为描述高温度区域中的夸克-胶子等离子体的框架，此时规范耦合较小，$g << 1$。 我回顾了对长程物理理解的最新进展，重点放在集体现象及其对规范相互作用屏蔽的影响。 我考虑了一些微扰理论中的红外发散，并讨论了消除这些发散的物理机制。 显示英文摘要

摘要： I discuss finite-temperature gauge theories as a framework to describe the quark-gluon plasma in the regime of high temperature where the gauge coupling is small, $g << 1$. I review recent progress in the understanding of the long-range physics, with emphasis on the collective phenomena and their consequences for the screening of the gauge interactions. I consider some of the infrared divergences of the perturbation theory, and discuss the physical mechanisms which remove these divergences.
