Abstract

The strong OZI allowed decays of the first radial excited states B(2S) and D(2S) are studied in the instantaneous Bethe-Salpeter method, and by using these OZI allowed channels we estimate the full decay widths: Γ_B⁰(2S)=24.4 MeV, Γ_B⁺(2S)=23.7 MeV, Γ_D⁰(2S)=11.3 MeV and Γ_D⁺(2S)=11.9 MeV. We also predict the masses of them: M_B⁰(2S)=5.777 GeV, M_B⁺(2S)=5.774 GeV, M_D⁰(2S)=2.390 GeV and M_D⁺(2S)=2.393 GeV.
