S. Albeverio, H. Gottschalk, J. -L. Wu

摘要:

一组截断Wightman函数的条件制定和示出允许的Hilbert空间结构的建设包括在Morchio-Strocchi修改Wightman公理。证明了由卷积广义白噪声构造的欧氏标量随机场和协变矢量(四元数)随机场的(截断)Schwinger函数解析延拓得到的截断Wightman函数满足这个条件。因此,这样的随机场提供了相对论模型的不定度规量子场论,在4维(矢量情况下),分别在所有维度(标量情况下)。

英文摘要:

A condition on a set of truncated Wightman functions is formulated and shown to permit the construction of the Hilbert space structure included in the Morchio--Strocchi modified Wightman axioms. The truncated Wightman functions which are obtained by analytic continuation of the (truncated) Schwinger functions of Euclidean scalar random fields and covariant vector (quaternionic) random fields constructed via convoluted generalized white noise, are then shown to satisfy this condition. As a consequence such random fields provide relativistic models for indefinite metric quantum field theory, in dimension 4 (vector case), respectively in all dimensions (scalar case).
