Ds0*(2317) and Ds1(2460) mesons in two-body B-meson decays

Abstract

We analyze the branching ratios of B→D(*)Ds0*(Ds1) decays using the factorization hypothesis. The B→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 fDs0* and fDs1 are calculated assuming a molecular structure for the Ds0* and Ds1 mesons. The calculated branching ratios of B-meson two-body decays are compared with experimental data and other theoretical results.
