Landau极大Abel插值规范下的Gribov模糊性

Gribov ambiguities at the Landau -- maximal Abelian interpolating gauge

A. D. Pereira, R. F. Sobreiro

摘要:

在以前的工作中,我们提出了一种新的方法来解释非阿贝尔规范理论中的Gribov模糊性。该方法包括一个额外的约束,直接消除了无穷小Gribov副本,而无需通常的几何方法上的介绍。这种策略允许用非厄米特Faddeev-Popov算子处理量规。在这项工作中,我们将这种方法应用到规范之间的朗道和最大阿贝尔规范插值。其结果是一个本地和功率计数可重正化的行动,免费的无穷小Gribov副本。此外,还导出了插值树级胶子传播子。

英文摘要:

In a previous work, we presented a new method to account for the Gribov ambiguities in non-Abelian gauge theories. The method consists on the introduction of an extra constraint which directly eliminates the infinitesimal Gribov copies without the usual geometric approach. Such strategy allows to treat gauges with non-hermitian Faddeev-Popov operator. In this work, we apply this method to a gauge which interpolates among the Landau and maximal Abelian gauges. The result is a local and power counting renormalizable action, free of infinitesimal Gribov copies. Moreover, the interpolating tree-level gluon propagator is derived.
