Abstract

A new dynamical symmetry breaking of SU(2)_L× U(1) caused by the combination of the axial-vector component and the fermion mass is found in electroweak theory. We obtain (m²_W=1/2g²m²_t) and (m²_Z=ρm²_W/cos²θ_W) with (ρ≃ 1), (G_F=1/2 √(2)m²_t)). Two fixed gauge fixing terms for W and Z boson fields are dynamically generated. Massive neutrinos are required.
