Production of DS0*(2317) and DS1(2460) in B decays as D(*)K and DS(*)η molecules

The molecular nature ofD(S0)*(2317) and D-S1(2460) have been extensively studied from the perspective of their masses, decay properties, and production rates. In this work, we study the weak decays of B -> (D) over bar D-(*)(S0)*(2317) and B -> (D) over bar D-(*)(S1)(2460) by invoking triangle diagrams where the B meson first decays weakly into (D) over bar ((*)) D-s((*)) and J/psi K(eta K-c), and then the D-S0*(2317) and D-S1(2460) are dynamically generated by the final-state interactions of D-s((*)) and D(*)K via exchanges of eta and D(*) mesons. The obtained absolute branching fractions of Br[B -> < <(D)over bar>D-(*)(S0)*(2317)] are in reasonable agreement with the experimental data, while the branching fractions of Br[B -> < <(D)over bar>D-(*)(S1)(2460)] are smaller than the experimental central values by almost a factor of two to three. We tentatively attribute such a discrepancy to either reaction mechanisms missing in the present work or the likely existence of a relatively larger c (s) over tilde component in the D-s1(2460) wave function.

Automated summary

The molecular nature of D(S0)*(2317) and D-S1(2460) has been studied extensively in terms of their masses, decay properties, and production rates. This study focuses on the weak decays of B -> (D) over bar D-(*)(S0)*(2317) and B -> (D) over bar D-(*)(S1)(2460) using triangle diagrams. The results show that the absolute branching fractions of B -> (D) over bar D-(*)(S0)*(2317) are in reasonable agreement with experimental data, while the branching fractions of B -> (D) over bar D-(*)(S1)(2460) are smaller than the experimental central values.
