Abstract

You might have heard about various mathematical properties of scattering amplitudes such as analyticity, sheets, branch cuts, discontinuities, etc. What does it all mean? In these lectures, we will take a guided tour through simple scattering problems that will allow us to directly trace such properties back to physics. We will learn how different analytic features of the S-matrix are really consequences of causality, locality of interactions, unitary propagation, and so on.

These notes are based on a series of lectures given in Spring 2023 at the Institute for Advanced Study in Princeton and the Higgs Centre School of Theoretical Physics in Edinburgh.

解析s矩阵的物理学

你可能听说过散射振幅的各种数学性质，如解析性、薄片、分支切割、不连续等。这一切意味着什么?在这些讲座中，我们将通过简单的散射问题进行引导，这将使我们能够直接将这些属性追溯到物理学。我们将学习s矩阵的不同解析特征是如何由因果关系、相互作用的局部性、酉传播等等所决定的。这些笔记是基于2023年春季在普林斯顿高等研究院和爱丁堡希格斯中心理论物理学院进行的一系列讲座。

期刊介绍： Physics Reports keeps the active physicist up-to-date on developments in a wide range of topics by publishing timely reviews which are more extensive than just literature surveys but normally less than a full monograph. Each report deals with one specific subject and is generally published in a separate volume. These reviews are specialist in nature but contain enough introductory material to make the main points intelligible to a non-specialist. The reader will not only be able to distinguish important developments and trends in physics but will also find a sufficient number of references to the original literature.
