Implications of the anomalous top quark couplings in $B_s$ - $\bar{B}_s$ mixing, $B \to X_{s} \gamma$ and top quark decays

Combined analysis of recent measured B s - B s mixing and B → X s γ decays provides constraints on the anomalous tsW couplings. We discuss the perspectives to examine the anomalous tsW couplings through Cabibbo-Kobayashi-Maskawa quark-mixing matrix-suppressed t →sW decays at the LHC.
