We apply Bogoliubov compensation principle to the problem of forward-backwardasymmetry in $t \bar t$ production at TEVATRON. The non-trivial solution ofcompensation equation for anomalous four-fermion interaction effectiveinteraction of doublets of heavy and light quarks leads to possibility ofexistence of $\bar t u,\, \bar b d$ vector bound states (resonance). Thecoupling of the bound state to $\bar t,\,u$ pair is calculated. With thisresult we obtain satisfactory description of totality of data on the effect ofFB asymmetry including slope of effect dependence on invariant $t \bar t$ mass.Predictions for the resonance mass and production cross-section at LHC arepresented.
