相对论欧几里德量子力学中的散射和反射正性

Scattering and reflection positivity in relativistic Euclidean quantum mechanics

W. N. Polyzou

摘要:

在本文中,我讨论的相对论性少粒子散射理论的动态输入是一个集合的反射正欧几里德协变格林函数的制定。相对论性量子力学的这种表述方式的优点是,所有的计算都可以用欧几里得变量来完成。希尔伯特空间内积的构造要求格林函数是反射正的,这是对动力学的非平凡约束。本文讨论反射正格林函数的结构。我表明,散射波运营商存在时,动力学是由格林函数的结构在这项工作中讨论。在这个欧几里德框架计算散射可观的技术进行了讨论。

英文摘要:

In this paper I discuss a formulation of relativistic few-particle scattering theory where the dynamical input is a collection of reflection-positive Euclidean covariant Green functions. This formulation of relativistic quantum mechanics has the advantage that all calculations can be performed using Euclidean variables. The construction of the Hilbert space inner product requires that the Green functions are reflection positive, which is a non-trivial constraint on the dynamics. In this paper I discuss the structure of reflection positive Green functions. I show that scattering wave operators exist when the dynamics is given by a Green function with the structure discussed in this work. Techniques for computing scattering observables in this Euclidean framework are discussed.
