Gribov拷贝与拓扑荷

Gribov copies and topological charge

B. Holdom

摘要:

格里波夫副本的存在是封闭规范理论场位形空间的一个中心特征。特别地,两个具有相对缠绕数的Gribov副本之间的跃迁意味着具有拓扑荷的时空构型。我们明确地证明了Gribov副本的增殖与相对缠绕数,我们的重点是在库仑规范的本地化(有限范数)配置。然后,我们讨论的可能性,一些对这样的副本连接的闵可夫斯基空间的解决方案。我们还评论了瞬子的相对重要性和禁闭的连接。

英文摘要:

The existence of Gribov copies is a central feature of the field configuration space of confining gauge theories. In particular a transition between two Gribov copies with relative winding number implies a space-time configuration with topological charge. We explicitly demonstrate the proliferation of Gribov copies with relative winding number, where our focus is on localized (finite norm) configurations in Coulomb gauge. We then discuss the likelihood that some pairs of such copies are connected by Minkowski space solutions. We also comment on the relative importance of instantons and the connection to confinement.
