الأصل · EN

We analyzed the decays of B⁺→ D⁰+D⁺sJ(2S) and B⁺→ D⁰+D⁺sJ(1D) by naive factorization method and model dependent calculation based on the Bethe-Salpeter method, the branching ratios are Br(D⁰D⁺sJ(2S))=(0.72±0.12)% and Br(D⁰D⁺sJ(1D))=(0.027±0.007)%. The branching ratio of decay B⁺→ D⁰D⁺sJ(2S)→ D⁰D⁰ K+ consist with the data of Belle Collaboration, so we conclude that the new state D⁺sJ(2700) is the first excited state D⁺sJ(2S).
