A Dynamical Origin of the Mass Hierarchy among Neutrinos, Charged   Leptons, and Quarks
  We propose a dynamical mass-generation scenario which naturally realizes the mass hierarchy among the neutrinos, charged leptons and quarks, where the mass is dominated by the self-mass induced through the anomalous (i.e. non-minimal) gauge interactions.
