AI总结:

本文探讨FLPR模型中与BRST相关的对称性,考虑Gribov歧义,通过全功能量化方法分析,发现由动作对称群生成的BRST相关变换家族,并揭示Gribov歧义导致初始对称群破坏,为QCD类似问题提供启示。

摘要:

随着近期复兴,文献中报道了FLPR模型的新特征。本文探索这些特征与QCD中涉及Gribov问题的联系。我们研究FLPR模型在一个最近提出的BRST相关对称性框架中,并对其进行全面的功能量化,作为考虑Gribov歧义的规范不变系统。我们获得由动作离散对称群生成的BRST相关变换家族。我们证明具有Gribov歧义的规范固定动作导致初始离散对称群的破坏。所获得的结果通过将两个系统之间的变量和场相应关联,为QCD中的类似问题提供了见解。

英文摘要:

With a recent revival, novel features of the FLPR model have been reported in the literature. A connection between those features to QCD involving the Gribov problem is explored. We investigate the FLPR model in a recently proposed framework of BRST-related symmetries and perform its full functional quantization as a gauge invariant system taking into account the Gribov ambiguities. We obtain a family of BRST-related transformations generated by the discrete group of symmetries of the action. We show that gauges possessing Gribov ambiguities lead to a violation of the initial discrete group of symmetries of the gauge-fixed action. The obtained results shed light into similar issues in QCD by the corresponding association of variables and fields between the two systems.
