Abstract：
In the framework of the SU(2)×U(1) gauge theory, we assume that there are two left-handed doublets, and tow neutral singlets of leptons After the spontaneous symmetry breaking, we have electron and its neutrino, a new charged heavy lepton and its neutrino, two neutral heavy leptons. We assume that the mass of the charged heavy lepton is between that of Z⁰ and W, and at least one of the neutral heavy leptons has a larger mass, then the radiative decay of Z⁰ can be understood.
