Ds0*(2317)andDs1(2460)mesons in two-bodyB-meson decays

Abstract

We analyze the branching ratios of $B\ensuremath{\rightarrow}{D}^{(*)}{D}_{s0}^{*}({D}_{s1})$ decays using the factorization hypothesis. The $B\ensuremath{\rightarrow}{D}^{(*)}$ 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.
