摘要：

We determine the constraints on the anomalous top-quark coupling associated with the flavor-changing neutral current vertex <(t)over bar c gamma> from the limits on the b-quark rare decay b --> s gamma and nonstandard top-quark decays. Based on these constraints, we discuss the experimental observability of the rare decay mode t --> c gamma, both at the Fermilab Tevatron with a luminosity upgrade and at the CERN LHC.
