摘　　要：The Large Hadron Collider at CERN is performing direct searches for top-quark anomalous flavorchanging neutral current(FCNC)processes.However,these processes may be correlated closely with the lowenergy rare B and K meson decays.In this paper,we review the anomalous top-quark coupling effects in these low-energy flavor transitions,summarize the flavor constraints and discuss their implications for direct detection of top-FCNC processes at the Large Hadron Collider.The Large Hadron Collider at CERN is performing direct searches for top-quark anomalous flavor-changing neutral current （FCNC） processes.
