Extensions of Higgs Universality in the Sterile Neutrino Sector

Application of Higgs Universality to the neutrino sector provides coupling between the active neutrino sector and the sterile neutrino sector. For either Hierarchy, this leads to predictions for the mass ratios in the sterile sector.  While the most natural result is that the ratios of sterile masses should be approximately the squares of the ratios of charged fermions, the ratios of the lighter masses can be modified.  We show how these results are obtained.
