| Abstract: | The possible variants of the unified models of electroweak interaction of leptons in the framework of the broken gauge SU(2) × U(1) × U′(1)-symmetry are constructed. In the first part analysis of SU(2) × U(1) × U′(1)-symmetry breaking by the different combinations of two types of Goldstone-Higgs fields: isodoublet φ and isosinglet Φ complex isovector ξ and Φ φ and ξ is considered. The second part is devoted to the construction of the feasible leptonic models in which the masses of the introduced leptons can be generated by symmetry breaking due to the fields considered in the first part. In the third part acceptability of these models from the point of view of available experimental data of cross-sections of muonic neutrino and antineutrino scattering on electron has been investigated. |
