论文摘要
在Landau仪表中四维Yang-Mills理论的精致的Gribov-Zwanziger方案中，从限制量规场配置到第一个Gribov地区，产生了Gluon质量术语。 Tissier和Wschebor指出，仅在通常的Faddeev-Popov动作中添加Gluon质量术语，就可以产生一环的重新归一化组改进的Gluon和Ghost Expagator，即使在红外线方面，也可以很好地与晶格数据一致。在这项工作中，我们将它们的分析扩展到了几种替代性重归其化方案，并展示了如何使用重新归一化方案依赖性来实现与Gluon和Ghost Ghost Expagtors的晶格数据几乎完美匹配。
Within the refined Gribov-Zwanziger scenario for four-dimensional Yang-Mills theory in the Landau gauge, a gluon mass term is generated from the restriction of the gauge field configurations to the first Gribov region. Tissier and Wschebor have pointed out that simply adding a gluon mass term to the usual Faddeev-Popov action yields one-loop renormalization group improved gluon and ghost propagators which are in good agreement with the lattice data even in the infrared regime. In this work, we extend their analysis to several alternative renormalization schemes and show how the renormalization scheme dependence can be used to achieve an almost perfect matching to the lattice data for the gluon and ghost propagators.
