Gribov问题与QCD动力学

The Gribov problem and QCD dynamics

N. Vandersickel, Daniel Zwanziger

摘要:

1967年,法捷耶夫和波波夫通过引入规范引入了一种叫做鬼的新粒子,从而推翻了杨-米尔斯理论。从那时起,这种量化就成了教科书上的标准项目。几年后,格里博夫发现规范固定并不完全,称为格里博夫副本的规范副本仍然存在,并且可以影响像规范依赖胶子和鬼传播子这样的量的红外区域。这一特点经常出现在与监禁有关的文学中。几年后,Gribov的半经典方法被推广到所有阶,所谓的GZ作用量诞生了。从那以后,许多相关的文章被发表。这篇评论倾向于对Gribov的思想和随后的GZ行动的建设进行教学评论,包括与Gribov地区有关的许多其他主题。它示出了如何GZ行动可以被视为一个非微扰的工具,它与其他方法对限制的关系。许多不同的功能相关的GZ行动应详细讨论,如BRST打破,KO标准,传播等,我们还将比较与晶格数据和其他非微扰的方法,包括随机量子化。

英文摘要:

In 1967, Faddeev and Popov were able to quantize the Yang-Mills theory by introducing new particles called ghost through the introduction of a gauge. Ever since, this quantization has become a standard textbook item. Some years later, Gribov discovered that the gauge fixing was not complete, gauge copies called Gribov copies were still present and could affect the infrared region of quantities like the gauge dependent gluon and ghost propagator. This feature was often in literature related to confinement. Some years later, the semi-classical approach of Gribov was generalized to all orders and the so-called GZ action was born. Ever since, many related articles were published. This review tends to give a pedagogic review of the ideas of Gribov and the subsequent construction of the GZ action, including many other toipics related to the Gribov region. It is shown how the GZ action can be viewed as a non-perturbative tool which has relations with other approaches towards confinement. Many different features related to the GZ action shall be discussed in detail, such as BRST breaking, the KO criterion, the propagators, etc. We shall also compare with the lattice data and other non-perturbative approaches, including stochastic quantization.
