The Mass Ratio Between Neutrinos and Charged Leptons

Abstract

In the framework of the recently proposed electroweak theory on a Planck lattice, we are able to solve approximately the lattice Dyson equation for the fermion self-energy functions and show that the large difference of charged lepton and neutrino masses is caused by their very different gauge couplings. The predicted mass ratio ($10^{-5}\sim 10^{-6}$) between neutrinos and charged lepton is compatible with present experiments.
