  It shows that because of the axial-vector coupling and the coupling with
fermions of different masses the untarity of the SM is broken at the scale of
10^{14}GeV. A new theory of EW interactions without Higgs is proposed. We
obtain M^2_W=g^2 m^2_t/2, M^2_Z=(g^2+g'^2)m^2_t/2, and G_F=1/(2\sqrt{2}m^2_t}.
