- Abstract
We apply Bogoliubov compensation principle to the problem of forward-backward asym-metry in tt production at TEVATRON. The nontrivial solution of compensation equation for anomalous four-fermion effective interaction of doublets of heavy and light quarks leads to possibility of existence of tu, bd. vector bound states (resonance). The coupling of the bound state to t, u pair is calculated. With this result we obtain satisfactory description of totality of data on the effect of FB asymmetry including slope of effect dependence on invariant tt mass. Predictions for the resonance mass and production cross-section at LHC are presented.
