Top-Quark Decay Via Flavor-Changing Neutral Currents at Hadron Colliders

Abstract

We study low energy experimental constraints on an anomalous top-quark coupling associated with the flavor-changing neutral current vertex $Z\bar{t}c$. In view of these constraints, we discuss the experimental observability of the induced rare decay mode $t\to Zc$, both at the Fermilab Tevatron (with the Main Injector or a luminosity-upgrade) and at the LHC.
