Abstract

We describe application of Bogoliubov compensation principle to calculation of non-perturbative contribution in the electroweak theory and QCD. We obtain unique solutions of compensation equations, which impose strong restrictions on parameters of theories and on functional dependence of corresponding form-factors. We calculate value of running gauge electroweak coupling αw(MW)=0.0374\alpha_w(M_W)=0.0374, that differs from the experimental value less than by 10%. We derive effective Nambu-Jona-Lasinio interaction from fundamental QCD and express its parameters in terms of initial QCD parameters: αs\alpha_s at low-momenta and current mass of light quarks. This leads to satisfactory description of low-mass hadron physics.
