Abstract

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-\Bbar_d,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.
