Abstract：
The concept of Bose Condensation of Higgs fields is applied to SU(2) Higgs φ⁴ model. It is proved that under the selfinteractions between Higgs fields, when the sum of condensation densities of charged complex fields and neutral complex fieldsremains fixed, the vaccum energies of symmetrical and asymmetrical condensations are equal to each other whereas the elementary excitation spectra all include three Goldstone particles and a particle with mass √2m. Then by introducing a coupling between massless electron and neutral Higgs field, we derive an expression of electron mass which coincides with that in Weinberg-Salam model.
