Abstract

A novel model of charged leptons is presented, which contains two basics hypotheses. The first hypothesis is that the Yukawa coupling between Higgs field and charged leptons is the weak interaction, the Higgs field is a scalar intermediate boson which changes the chirality of charged leptons in the weak interaction. The other hypothesis is that the flavor eigenstates of charged leptons are the superposition states of left-handed and right-handed elementary Weyl spinors before the electroweak symmetry breaking. According to this model, the Yukawa coupling constants between Higgs field and three generations of charged leptons are considered to be a universal constant, and the difference of the masses of different charged leptons is due to the different left-right mixing angles of their flavor eigenstates.

Highlights

Up to now, with the discovery of the 125 GeV Higgs boson in 2012 at the CERN LHC [1] [2], the Weinberg-Salam (WS) model [3] [4] of the electroweak interaction of particle physics stands triumphant, and almost all relevant experimental results in particle physics are consistent with this model

Summary

Introduction

With the discovery of the 125 GeV Higgs boson in 2012 at the CERN LHC [1] [2], the Weinberg-Salam (WS) model [3] [4] of the electroweak interaction of particle physics stands triumphant, and almost all relevant experimental results in particle physics are consistent with this model. The WS model has achieved impressive success in correlating all observed low-energy data in terms of a very few parameters, it cannot be called perfect. The success of the WS model only involves the gauge sector of the theory, in which only one free parameter, the Weinberg angle θW , is used to understand numerous neutral-current data. We do not know why there exists such a large difference. Since the fermion masses are related to the Yukawa couplings, we can only understand these differences and the mass-generation phenomenon by studying the Yukawa couplings in detail [5] [6] [7] [8]
