Abstract
We construct a Z8 model for leptons where all Yukawa couplings are of order unity, but known lepton masses are generated radiatively, order by order. The seed is provided by fourth generation leptons E and N, and two additional Higgs doublets are introduced to give nearest-neighbor Yukawa couplings. Loop masses are generated when Z8 is softly broken down to Z2, while me and m generation require Higgs bosons to be weak scale. The Z2 symmetry forbids e. The most stringent bound comes from e. The model has implications for e, ee conversion, ee, and FCNC decays of E and N (such as Ee). © 1994 The American Physical Society.
