A Causal Approach to Massive Yang-Mills Theories
Frank Krahe
We study quantized Yang-Mills theory with massive vector fields in the framework of causal perturbation theory. The most general form of the interaction which is invariant under op…

On the Algebra of Ghost Fields
F. Krahe
We study in detail the algebra of free ghost fields which we realize in a Hilbert-Fock space with positive metric. The investigation of causality clarifies the exact reason for the…
