任意表象中威尔逊圈算符的非阿贝尔Stokes定理及其对夸克禁闭的意义

Non-Abelian Stokes theorem for the Wilson loop operator in an arbitrary representation and its implication to quark confinement

Ryutaro Matsudo, Kei-Ichi Kondo

摘要:

通过威尔逊圈算符给出了$SU(N)$ Yang-Mills理论中磁单极子的规范无关定义。为此,我们给出了$SU(N)$规范群的任意表示中的威尔逊圈算子的非阿贝尔Stokes定理的Diakonov-Petrov形式的显式证明,从而导出了非阿贝尔Stokes定理的一种新形式.新的形式以规范不变的方式提取了磁场对威尔逊圈算符的贡献,使我们能够从对偶超导真空的观点讨论夸克在任何表象中的禁闭.

英文摘要:

We give a gauge-independent definition of magnetic monopoles in the $SU(N)$ Yang-Mills theory through the Wilson loop operator. For this purpose, we give an explicit proof of the Diakonov-Petrov version of the non-Abelian Stokes theorem for the Wilson loop operator in an arbitrary representation of the $SU(N)$ gauge group to derive a new form for the non-Abelian Stokes theorem. The new form is used to extract the magnetic-monopole contribution to the Wilson loop operator in a gauge-invariant way, which enables us to discuss confinement of quarks in any representation from the viewpoint of the dual superconductor vacuum.
