Top-quark decay via flavor-changing neutral currents at hadron colliders Original Research Article

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