2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/40771We explored various cases for the branching ratios (BRs) of $B_s\to K^+K^-$, $B_s\to K^0\bar{K}^0$ and $B_d\to π^+ π^-$ decays. We study the possibility of determining $γ$ by using the following the measurements: (a) BRs of $B_s\to K^+K^-$, and $B_s\to K^0\bar{K}^0$; (b) the ratio of direct CP asymmetries in $B_d\to π^+ π^-$ and $B_s\to K^+K^-$; (c) the mix-induced CP asymmetry in $B_d\to π^+ π^-$; and (d) the angle of $β$.12 pages, 5 figuresHigh Energy Physics - Phenomenologytext
