捏法简介

Introduction to the Pinch Technique

Vincent Mathieu

摘要:

这些笔记是对捏技术的简短介绍。本文给出了QCD格林函数的单圈计算。箍缩技术和背景场方法之间的等价性明确显示在一个回路的水平。我们在最后一节中回顾了吸收箍缩技术。这些讲座是关于这一主题的相关论文的汇编,并为第三届Modave暑期学校数学物理准备。

英文摘要:

These notes are a short introduction to the pinch technique. We present the one-loop calculations for basic QCD Green's functions. The equivalence between the pinch technique and the background field method is explicitly shown at the one-loop level. We review the absorptive pinch technique in the last sections. These lectures are a compilation of relevant papers on this subject and are prepared for the third Modave Summer School in Mathematical Physics.
