Understanding the nature of Ds(2317) and Ds(2460) through nonleptonic B decays

We consider the nonleptonic B decays B --> (DDS)-D-(*)(2317) and B --> (DDS)-D-(*)(2460), involving the newly discovered D-S (2317) and the D-S(2460) states. We find that experiments indicate disagreement with model calculations of their properties and/or breakdown of the factorization assumption for these decays. We point out that decays involving B-S mesons where the D-S resonances can be produced via the weak decay of the b quark can provide further information about the nature of these newly discovered states. We also propose a model to calculate the two body nonleptonic decays B --> D-(*) D-S(2317) D-S (2460)), if the D-S(2317) and D-S(2460) are interpreted as DK and D* K molecules.
