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.

  1. The $B^{+(0)} \to \bar D^{0(-)} D^{*}_{s0}(2317)^+$ decays and the molecular structure of $D^*_{s0}(2317)$

    hep-ph 2025-12 conditional novelty 6.0 of 10

    Using B→D D K data and a two-parameter model, the authors derive B→D D*_s0(2317) branching fractions that agree with experiment within errors, supporting a sizable DK molecular component of D*_s0(2317).

  2. Implication of the existence of $J^{PC}=0^{--}$ $\bar{D}_sDK$ bound state on nature of $D_{s0}^*(2317)$ and new configuration of exotic state

    hep-ph 2025-01 conditional novelty 6.0 of 10

    A J^PC = 0^-- anti-D_s D K three-meson bound state, X(4310), is predicted and shown to be searchable in B+ -> D*± D∓ K+ decays at LHCb.

  3. Decay constants of the two-pole $D_0^*(2300)$

    hep-ph 2026-07 conditional novelty 4.0 of 10

    Molecular two-pole D0*(2300) decay constants are 65 and 81 MeV—much smaller than compact c¯q estimates—and imply Cabibbo-favored b-hadron branching fractions of order 10^{-5}.
