A new symmetry breaking, axial-vector symmetry breaking, is found. M^{2}_{W}=1/2g^{2}m^{2}_{t}, m^{2}_{Z}=ρm^{2}_{W}/cos^{2} θ, and G_{F}=1/(2\sqrt{2}m^{2}_{t}) are obtained and they agree with data. It has been proved that the theory is renormalizable and unitary.31 pagesHigh Energy Physics - Phenomenologytext
