不定度规量子场的散射理论

Scattering theory for quantum fields with indefinite metric

S. Albeverio, H. Gottschalk

摘要:

本文讨论具有不定度规的局域相对论量子场的散射理论。由于Haag-Ruelle理论的结果不能推广到不定度规的情形,我们提出了一个构造内态和外态的公理化框架,使得LSZ渐近条件可以从这些假设中推导出来.这种构造的中心数学对象是局部、内场和外场的混合真空期望值的集合,称为"形状因子泛函“,这是满足希尔伯特空间结构条件所必需的。给定一个具有多项式传递函数的散射矩阵,我们构造了一个内插的、局域的、具有不定度规的相对论性量子场,它适合于给定的散射框架。

英文摘要:

In this work, we discuss the scattering theory of local, relativistic quantum fields with indefinite metric. Since the results of Haag--Ruelle theory do not carry over to the case of indefinite metric, we propose an axiomatic framework for the construction of in- and out- states, such that the LSZ asymptotic condition can be derived from the assumptions. The central mathematical object for this construction is the collection of mixed vacuum expectation values of local, in- and out- fields, called the ``form factor functional'', which is required to fulfill a Hilbert space structure condition. Given a scattering matrix with polynomial transfer functions, we then construct interpolating, local, relativistic quantum fields with indefinite metric, which fit into the given scattering framework.
