Abstract Within the Standard Model, the branching fraction of the rare decay B s → K 0 K ¯ 0 $$ {B}_s\to {K}^0{\overline{K}}^0 $$ is related to other decay rates and CP asymmetries through the approximate SU(3) flavor symmetry of the strong interactions and the heavy-quark limit. Three such relation...
