Studies of D[sub sJ][sup (∗)] Production in B Decays and e+e− → cc̄ Events

We report a study of $D*_{sJ}(2317)^+ and D_{sJ}(2460)^+$ meson production in B decays. We observe and measure branching fractions for the decays $B^+ \to D^{(*)+}_{sj} \bar{D}^{(*)0}$ and $B^0 \to D^{(*)+}_{sj} \bar{D}^{(*)-}$ with the subsequent decays $D^*_{sJ}(2317)^+ \to D^+_s \pi^0, D_{sJ}(2460)^+ \to D^{*+}_s \pi^0$ and D_{sJ} (2460)^+ \to D^+_s \gamma$
