Abstract

It is shown that for a magnetic monopole in an SU(2) gauge theory, interacting with an arbitrary number of massless doublets of fermions, the global and the local conservation laws of the full four-dimensional theory, together with the restrictions on the fermions to J=0 partial wave, uniquely determine the final state for a given initial state. As a result, monopole-induced baryon-number nonconservation is a necessary consequence of the conservation laws of the system. The modification of the conservation laws in the presence of the full SU(5) gauge interactions is discussed.
