Abstract

We construct a concise U(1)X Froggatt-Nielsen model in which baryon triality, a discrete gauge Z3 symmetry, arises from U(1)X breaking. The proton is thus stable, however, R-parity is violated. With the proper choice of U(1)X charges we can obtain neutrino masses and mixings consistent with an explanation of the atmospheric and solar neutrino anomalies in terms of neutrino oscillations, with no right-handed neutrinos required. The only mass scale apart from Mgrav is m3/2 ~ msoft.
