Lessons from the LHCb measurement of CP violation in $B_s\to K^{+}{K}^{-}$

Yosef Nir, Inbar Savoray, Yehonatan Viernik

The LHCb experiment measured the time-dependent CP asymmetries $C_{KK}$ and $S_{KK}$ in $B_s\to K^{+}{K}^{-}$ decay. Combining with the corresponding CP asymmetries $C_{\pi \pi }$ and $S_{\pi \pi }$…
