$D_{s0}^{*}(2317)$ and $D_{s1}(2460)$ mesons in two-body $B$-meson decays

We analyze the branching ratios of $B\to D^{(*)}{D}_{s0}^{*}(D_{s1})$ decays using the factorization hypothesis. The $B\to D^{(*)}$ transition form factors are taken from a model-independent analysis done by Caprini, Lellouch, and Neubert based on heavy quark spin symmetry and dispersive constraints, including short-distance and power corrections. The leptonic decay constants $f_{D_{s0}^{*}}$ and $f_{D_{s1}}$ are calculated assuming a molecular structure for the $D_{s0}^{*}$ and $D_{s1}$ mesons. The calculated branching ratios of $B$-meson two-body decays are compared with experimental data and other theoretical results.
