NONPERTURBATIVE SOLUTIONS IN THE ELECTROWEAK THEORY WITH $\bar t t$ CONDENSATE AND THE t-QUARK MASS

Abstract

We apply Bogoliubov compensation principle to the gauge electroweak interaction. The nontrivial solution of compensation equations for anomalous three-boson gauge invariant effective interaction uniquely defines its form-factor and parameters of the theory including value of gauge electroweak coupling [Formula: see text] in satisfactory agreement with the experimental value. A possibility of spontaneous generation of effective four-fermion interaction of heavy quarks is demonstrated. This interaction defines an equation for a scalar bound state of heavy quarks which serve as a substitute for the elementary scalar Higgs doublet. As a result we calculate the t-quark mass mt = 177 GeV in satisfactory agreement with the experimental value. The results strongly support idea of [Formula: see text] condensate as a source of the electroweak symmetry breaking. The approach predicts heavy composite Higgs scalar MH ≃ 1800 GeV .
