New dynamical gauges of the SM of EW interactions

Abstract

A new Lagrangian of EW interactions without spontaneous symmetry breaking, Higgs, and Fadeev-Popov procedure has been constructed. It consists of three parts: $SU(2{)}_L\times U(1)$ gauge fields, massive fermion fields, and their interactions. In this theory the gauge coupling constants g, g', and fermion masses are the inputs. A new mechanism of $SU(2{)}_L\times U(1)$ symmetry breaking caused by fermion masses has been found. In the EW theory top quark mass plays a dominant role. This mechanism leads to nonperturbative generation of the gauge fixings and masses of Z and W fields. $m_W^2=\frac{1}{2}{g}^2{m}_t^2,m_Z^2=\frac{1}{2}{\bar{g}}^2{m}_t^2,G_F=\frac{1}{2\sqrt{2}{m}_t^2}$ are revealed from this theory. The propagators of Z- and W-fields without quadratic divergent terms are derived. Very heavy neutral and charged scalars are dynamically generated from this theory too.
