| dc.description | The problem of possible deviations from the Standard Model is considered in the framework of a variant of dynamical electroweak symmetry breaking. The parameters of the theory are obtained, which describe deviations from SM in $Z\to \bar b b$ decay, are also consistent with leptonic left-right asymertry (SLAC data) and with the existence of a nontrivial solution for vertex $\bar t (Z,γ) c$. The occurrence of this solution leads to a significant enhancement in neutral flavor changing transition $t\to c$. The intensity of this transition is connected with the $c$-quark mass, that leads to estimates of probabilities of exotic decays $t\to c (Z,γ)$ (few %) and of the cross-section of a single $t$-quark production in process $e^+e^-\to t \bar c$ at LEP2 ($\simeq 0.03 pb$ at $\sqrt{s} = 190 GeV$). The model is shown to be consistent with the totality of the existing data; the predictions allow its unambiguous check. | |
