Abstract

In this work, we build a model to combine the mass generated from the Higgs mechanism and that from the dynamical chiral symmetry breaking mechanism. This is motivated by the fermion mass hierarchy that the neutrino mass is smaller than the charged lepton mass and the charged lepton mass is smaller than the quark mass. Since they participate different interactions, it is natural to conjecture that interactions contribute to the fermion mass. This conjecture could be explained via the dynamical chiral symmetry breaking mechanism with assuming the existence of a non-perturbative regime. In addition, this model predicts a different ratio of fermion Yukawa coupling to the Higgs self coupling, which could be verified in the near future.
