Study ofB→DsJ(*)+D¯(*)Decays

We report a study of $D_{sJ}^{*}(2317{)}^{+}$ and $D_{sJ}(2460{)}^{+}$ meson production in $B$ decays. We observe the decays $B^{+}\to D_{sJ}^{(*)+}{\overline{D}}^{(*)0}$ and $B^0\to D_{sJ}^{(*)+}{D}^{(*)-}$ with the subsequent decays $D_{sJ}^{*}(2317{)}^{+}\to D_s^{+}{\pi }^0$, $D_{sJ}(2460{)}^{+}\to D_s^{+}\gamma$, and $D_{sJ}(2460{)}^{+}\to D_s^{*+}{\pi }^0$. Based on a data sample of $122.1\times {10}^6$ $B\overline{B}$ pairs collected with the BABAR detector at the PEP-II $B$ factory, we obtain branching fractions for these modes, including the previously unseen decays $B\to D_{sJ}^{(*)+}{D}^{*}$. In addition, we perform an angular analysis of $D_{sJ}(2460{)}^{+}\to D_s^{+}\gamma$ decays to test the different $D_{sJ}(2460{)}^{+}$ spin hypotheses.
