Abstract
We show how Majorana neutrino masses can be radiatively generated, in model where charged lepton masses are radiatively induced, order by order, from heavy sequential lepton seeds. Only the new sequential neutral lepton has a right-handed partner, and its Majorana mass provides the seeds for Majorana neutrino mass generation. Saturating the cosmological bound of 50 eV with mντ we find that mνμ and mνe could be at most 10-2, and 10-3eV, respectively. The electron neutrino mass may vanish in the limit of degenerate charged Higgs bosons. Unfortunately, νe-ντ mixing is also radiatively induced, and is too smallk for the sake of solving the solar neutrino problem via the Mikheyev-Smirnov-Wolfenstein effect. © 1994.
