Top-quark flavor-changing tqZ couplings and rare $$\Delta F=1$$ ΔF=1 processes

Abstract We study the impacts of anomalous tqZ couplings ($$q=u,c$$ q=u,c ), which lead to the $$t\rightarrow q Z$$ t→qZ decays, on low energy flavor physics. It is found that the tuZ-coupling effect can significantly affect the rare K and B decays, whereas the tcZ-coupling effect is small. Using th...
