Abstract

We devise minimalistic gauged U(1)X Froggatt–Nielsen models which at low-energy give rise to the recently suggested discrete gauge Z6-symmetry, proton hexality, thus stabilizing the proton. Assuming three generations of right-handed neutrinos, with the proper choice of X-charges, we obtain viable neutrino masses. Furthermore, we find scenarios such that no X-charged hidden sector superfields are needed, which from a bottom–up perspective allows the calculation of gstring, gX and GSM's Kač–Moody levels. The only mass scale apart from Mgrav is msoft.
