Abstract

Violation of baryon, lepton and, in general, fermion number is central to the hypothesis of quark lepton unification in a gauge context. Three of its characteristic signatures are proton decay, n-n oscillation and neutrinoless double β decay. In 1974 and 1975 it was shown that within maximal gauging the proton may decay via four alternative modes (i. e. proton → one or three leptons or anti-leptons) satisfying ΔF = −2, 0, −4 and −6 some of which may coexist; the deuteron may decay into pions and neutrinoless double β decay may occur in the context of spontaneous gauge symmetry breaking. It is now observed that n-n̄ oscillations (which are related to deuteron decays into pions) can coexist with proton decay of especially ΔF = −4 variety (p → e+πr0) and both these processes may possess measurable strength so as to be amenable to forthcoming searches.
