A new way of probing new physics in the B meson system is provided. We define double ratios for the observables of B d,s -Bd,s mixings and B d,s → μ + μ − decays, and find simple relations between the observables. By using the relations we predict the yet-to-be-measured branching ratio of B d → μ + μ − to be (0.809-1.03)×10 −10 , up to the new physics models.
