Spontaneous Breakdown of Weak and Electromagnetic Interaction Symmetry

Abstract

A unified theory of the weak and electromagnetic interactions of leptons and hadrons is constructed. The underlying symmetry group is taken to be the $\mathrm{SU}\left(2\right)\mathrm{}$ generated by the weak lepton currents and the hadronic Cabibbo currents. This symmetry is destroyed by the spontaneous breakdown mechanism. In our theory, the weak coupling constant is the same as the electromagnetic coupling constant, and the mass of the charged intermediate boson is 37.4 GeV.
