有质量规范场理论类引力描述中的规范不变性

Gauge invariance in gravity-like descriptions of massive gauge field theories

Dennis D. Dietrich

摘要:

本文讨论了四维时空中大质量阿贝尔和非阿贝尔规范场理论的类引力公式,特别强调了规范不变性的问题。分别分析了用反对称张量场和几何变量表示的不同描述。在这两种方法中,Stückelberg自由度因子都被排除在外。我们还证明,在阿贝尔的情况下,规范传播子的无质量极限,这是不存在的矢量位公式,是明确的反对称张量字段。

英文摘要:

We discuss gravity-like formulations of massive Abelian and non-Abelian gauge field theories in four space-time dimensions with particular emphasis on the issue of gauge invariance. Alternative descriptions in terms of antisymmetric tensor fields and geometric variables, respectively, are analysed. In both approaches Stückelberg degrees of freedom factor out. We also demonstrate, in the Abelian case, that the massless limit for the gauge propagator, which does not exist in the vector potential formulation, is well-defined for the antisymmetric tensor fields.
