Baryon Triality and Neutrino Masses from an Anomalous Flavor U(1)

Herbi K. Dreiner, Christoph Luhn, Hitoshi Murayama +1

We construct a concise U(1)_X Froggatt-Nielsen model in which baryon triality, a discrete gauge Z_3 symmetry, arises from U(1)_X breaking. The proton is thus stable, however, R-par…
