重整化与量子场论

Renormalization and quantum field theory

R. E. Borcherds

摘要:

本文的目的是描述如何利用正则化和重整化从拉格朗日量构造微扰量子场论。我们首先定义了重整化和Feynman测度,并证明了虽然不一定存在正则Feynman测度,但在重整化下存在Feynman测度的正则轨道。然后,我们构建了一个微扰的量子场论从拉格朗日和费曼措施,并证明它满足微扰类似的怀特曼公理,扩展到允许时间有序复合运营商在弯曲的时空。

英文摘要:

The aim of this paper is to describe how to use regularization and renormalization to construct a perturbative quantum field theory from a Lagrangian. We first define renormalizations and Feynman measures, and show that although there need not exist a canonical Feynman measure, there is a canonical orbit of Feynman measures under renormalization. We then construct a perturbative quantum field theory from a Lagrangian and a Feynman measure, and show that it satisfies perturbative analogues of the Wightman axioms, extended to allow time-ordered composite operators over curved spacetimes.
