The Principles of Gauging
摘要：
本文的目的是双重的：第一，提出一个检查的原则基础规范场理论。我认为有两个原则直接连接到两个著名的定理埃米诺特关于整体和局部对称性的自由物质场拉格朗日，在下文中被称为“守恒原理”和“规范原理”。由于这两种方法只表达了自由场论的某些对称性特征，它们不足以导出与新规范场的真正相互作用耦合。为此目的，有必要提倡第三个真正经验的原则，它可以被理解为等效原则的一般化。本文的第二个任务是根据所提出的规范理论的逻辑结构来处理规范势的实在性地位的本体论问题。在规范理论中拓扑效应的非定域解释，以及规范势的非实在性与广义等效原理的一致性将受到青睐。
英文摘要：
The aim of this paper is twofold: First, to present an examination of the principles underlying gauge field theories. I shall argue that there are two principles directly connected to the two well-known theorems of Emmy Noether concerning global and local symmetries of the free matter-field Lagrangian, in the following referred to as "conservation principle" and "gauge principle". Since both these express nothing but certain symmetry features of the free field theory, they are not sufficient to derive a true interaction coupling to a new gauge field. For this purpose it is necessary to advocate a third, truly empirical principle which may be understood as a generalization of the equivalence principle. The second task of the paper is to deal with the ontological question concerning the reality status of gauge potentials in the light of the proposed logical structure of gauge theories. A nonlocal interpretation of topological effects in gauge theories and, thus, the non-reality of gauge potentials in accordance with the generalized equivalence principle will be favoured.
