New Physics in Bd,ₛ-,ₛ mixings and Bd,ₛ→μ+μ- decays

Lee, Jong-Phil

Original · EN

A new way of probing new physics in the B meson system is provided. We define double ratios for the observables of Bd,ₛ-,ₛ mixings and Bd,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 Bd→μ+μ- to be (0.809 1.03)× 10⁻¹⁰, up to the new physics models.
