Search for Anomalous Top--Quark Interaction at LEP-2 Collider

Abstract

We show that a search for $e^{+}{e}^{-}\to t\bar{q}$ $(\bar{q}=\bar{c},\bar{u})$ events at LEP--2 collider provide a possibility to improve significantly the modern constraints on coupling constants of anomalous $t$--quark interaction via flavor--changing neutral currents.
