This dualized theory is in both a unitary and renormalizable gauge: The self-dual field strength has exactly the three components necessary to describe a massive vector field. In future work we shall utilize this new formulation as a calculational tool in spontaneously broken gauge theories.11 pages, tex, clarified title, abstract, body, and referencesHigh Energy Physics - Theorytext
