A space-time model of isospace

Abstract

The principle of combined inversion indicates a close relationship between isospace and ordinary space. The possible nature of this relationship is demonstrated with the help of a model, in which the isospin, baryon number, hypercharge and charge conjugation operators appear as displacement operators, producing rotations within space-time itself. In the model the asymmetry of isospace appears as a consequence of relativistic covariance, and charge conjugation and parity appear as continuous transformations.
