用关联函数构造非微扰规范

Constructing non-perturbative gauges using correlation functions

Axel Maas

摘要:

在非阿贝尔规范理论的非微扰域中,规范固定受到Gribov-Singer模糊性的阻碍。为了比较不同方法的结果,有必要明确地解决这种模糊性。这样的决议提出了使用的条件关联函数的一个家庭的非微扰朗道规范。因此,各种结果可用于关联函数可能对应于不同的非微扰朗道规范,区分由一个额外的非微扰规范参数。的建议,必要的假设,并从格点规范理论计算的证据,详细介绍。

英文摘要:

Gauge fixing in the non-perturbative domain of non-Abelian gauge theories is obstructed by the Gribov-Singer ambiguity. To compare results from different methods it is necessary to resolve this ambiguity explicitly. Such a resolution is proposed using conditions on correlation functions for a family of non-perturbative Landau gauges. As a consequence, the various results available for correlation functions could possibly correspond to different non-perturbative Landau gauges, discriminated by an additional non-perturbative gauge parameter. The proposal, the necessary assumptions, and evidence from lattice gauge theory calculations, are presented in detail.
