Fermion transmutation - a renormalization effect in gauge theory

Abstract

A new category of phenomena is predicted in which fermions of different flavours can transmute into one another, for example $e\to \mu$ or $e\to \tau$, as a consequence of the `rotating' mass matrix due to renormalization. As examples, calculations will be presented for various such processes. Some of these could be accessible to experiments in the near future.
