Radiative Lepton Masses with Heavy Lepton Seed
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 , which receive (Dirac) mass in usual way. Two additional Higgs doublets with nontrivial Z8 charge are introduced to give nearest neighbor Yukawa couplings. Hence, nonstandard Higgs bosons ...
متن کاملThe Problem of Quark and Lepton Masses
Different approaches to the fermion mass problem are reviewed. We illustrate these approaches by summarizing recent developments in models of quark and lepton mass matrices. Dynamical calculations of the top quark mass are discussed, based on (a) infrared quasi-fixed points of the renormalisation group equations, and (b) the multiple point criticality principle in the pure Standard Model. We al...
متن کاملQuark and lepton masses from Gaussian landscapes.
The flavor structure of the standard model (SM) might arise from random selection on a landscape. We propose a class of simple models, "Gaussian landscapes," where Yukawa couplings derive from overlap integrals of Gaussian wave functions on extra-dimensions. Statistics of vacua are generated by scanning the peak positions of these zero-modes, giving probability distributions for all flavor obse...
متن کاملNeutrino, Lepton, and Quark Masses in Supersymmetry
The recently proposed model of neutrino mass with no new physics beyond the TeV energy scale is shown to admit a natural and realistic supersymmetric realization, when combined with another recently proposed model of quark masses in the context of a softly broken U(1) symmetry. Four Higgs doublets are required, but two must have masses at the TeV scale. New characteristic experimental predictio...
متن کاملEvidence for radiative generation of lepton masses
We present a fit to the experimental charged lepton masses as coming from radiative corrections in QED.
