重叠Wilson线的功率发散

Power Divergences in Overlapping Wilson Lines

Matthias Berwein

摘要:

以循环威尔逊圈为例,讨论了部分重叠段的威尔逊线算子的发散结构。广义指数定理被用来显示幂发散的指数和因式分解的某些线性组合相关联的循环功能。

英文摘要:

We discuss the divergence structure of Wilson line operators with partially overlapping segments on the basis of the cyclic Wilson loop as an explicit example. The generalized exponentiation theorem is used to show the exponentiation and factorization of power divergences for certain linear combinations of associated loop functions.
