Description
We devise minimalist U(1)_X Froggatt-Nielsen models which give rise to the recently
proposed low-energy discrete gauge symmetry "proton hexality". The proton is thus
stable. In addition, having three generations of right-handed neutrinos we can obtain
viable neutrino masses.
Furthermore one can find scenarios such that no X-charged hidden sector superfields
are needed, which, from a bottom-up perspective, allows the calculation of the
string coupling constant g_string. The only mass scale apart from M_grav is m_soft.
