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

摘要

Combined analysis of recent measured $\bs$ mixing and $B \to X_s \gamma$decays provides constraints on the anomalous $\bar{t}sW$ couplings. We discussthe perspectives to examine the anomalous $\bar{t}sW$ couplings throughCKM-suppressed $ t \to s W$ decays at the LHC.
