The Decays of $B^{+}\to {\bar{D}}^0+D_{sJ}^{+}(2S)$ and $B^{+}\to {\bar{D}}^0+D_{sJ}^{+}(1D)$

We analyzed the decays of $B^{+}\to {\bar{D}}^0+D_{sJ}^{+}(2S)$ and $B^{+}\to {\bar{D}}^0+D_{sJ}^{+}(1D)$ by naive factorization method and model dependent calculation based on the Bethe-Salpeter method, the branching ratios are $Br({\bar{D}}^0{D}_{sJ}^{+}(2S))=(0.72\pm 0.12)$ and $Br({\bar {D}^0}D^{+}{sJ}(1D))=(0.027\pm0.007)%$\mathrm{.}Thebranchingratioofdecay$B^{+}\to {\bar {D}^0}D^{+}{sJ}(2S)\to {\bar {D}^0}D^0 K^+$ consist with the data of Belle Collaboration, so we conclude that the new state $D_{sJ}^{+}(2700)$ is the first excited state $D_{sJ}^{+}(2S)$.
