A new mechanism for generating an ultralight Dirac neutrino is given. A discussion is given of how it might possibly arise in a supergrand unified theory (SUSY GUT) with a geometric type of a hierarchy. The neutrino is scaled in mass relative to its charge-23 family member by Mₒₔₒₘ{M₆ₔₓ}.
Roy et al. (Mon,) studied this question.
