标题： Differential Renormalization of Gauge Theories

摘要： 约束微分重整的范围是为费曼图提供重整化的表达式，同时保持理论的Ward恒等式。 最近已经证明，至少在单环情况下，对于阿贝尔和非阿贝尔规范理论可以一致地完成这一过程。 我们简要回顾这些结果，以胶子自能为例，在坐标空间和动量空间中进行评估，并对异常情况进行评论。 显示英文摘要

摘要： The scope of constrained differential renormalization is to provide renormalized expressions for Feynman graphs, preserving at the same time the Ward identities of the theory. It has been shown recently that this can be done consistently at least to one loop for abelian and non-abelian gauge theories. We briefly review these results, evaluate as an example the gluon selfenergy in both coordinate and momentum space, and comment on anomalies.
