Abstract
We analyzed the decays of B+→D¯0+DsJ+(2S) and B+→D¯0+DsJ+(1D) by naive factorization method and model dependent calculation based on the Bethe-Salpeter method, the branching ratios are Br(D¯0DsJ+(2S))=(0.72±0.12)% and Br(D¯0DsJ+(1D))=(0.027±0.007)%. The branching ratio of decay B+→D¯0DsJ+(2S)→D¯0D0K+ consists with the data of Belle Collaboration, so we conclude that the new state DsJ+(2700) is the first excited state DsJ+(2S).
