Branching ratios of $B_s\to (K^{+}{K}^{-},K^0{\bar{K}}^0)$ and $B_d\to π^+ π^- and determination of \boldmath{$γ(ϕ_3)$

Chuan-Hung Chen, C. Q. Geng

We explored various cases for the branching ratios (BRs) of $B_s\to K^{+}{K}^{-}$, $B_s\to K^0{\bar{K}}^0$ and $B_d\to {\pi }^{+}{\pi }^{-}$ decays. We study the possibility of determining $\gamma$ by using…
