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

Understand

We analyze the branching ratios of B to D(*) + Ds0*(Ds1) 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 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.
