面向粒子物理学家的共形场论

Conformal field theory for particle physicists

Marc Gillioz

AI总结:

本套共形场论入门讲义从闵可夫斯基时空幺正量子场论视角出发,以怀特曼公理为起点讲解共形对称性相关内容直至现代共形自举,补充了多数综述遗漏的多个关键主题。

摘要:

这是一套关于共形场论(CFT)的入门讲义。与现有多数该主题综述不同,本书从闵可夫斯基时空中的幺正量子场论视角来介绍CFT。内容从量子场论的非微扰表述(怀特曼公理)起步,随后逐步聚焦于标度对称性和特殊共形对称性的推论,一直延伸到现代共形自举方法。该路径涵盖了常被遗漏的主题,比如闵可夫斯基时空中共形变换的微妙之处、位置空间与动量空间中怀特曼函数和时序关联函数的构建、由谱表示推导的幺正性界,以及紫外(UV)和红外(IR)发散的出现。

英文摘要:

This is a set of introductory lecture notes on conformal field theory. Unlike most existing reviews on the subject, CFT is presented here from the perspective of a unitary quantum field theory in Minkowski space-time. It begins with a non-perturbative formulation of quantum field theory (Wightman axioms), and then gradually focuses on the implications of scale and special conformal symmetry, all the way to the modern conformal bootstrap. This approach includes topics often left out, such as subtleties of conformal transformations in Minkowski space-time, the construction of Wightman functions and time-ordered correlators both in position- and momentum-space, unitarity bounds derived from the spectral representation, and the appearance of UV and IR divergences.
