B Decays

We consider the nonleptonic B decays B ! D(�)Ds(2317) and B ! D(�)Ds(2460), involving the newly discovered Ds(2317) and the Ds(2460) states. We find that experiments indicate disagree- ment with model calculations of their properties and/or breakdown of the factorization assumption for these decays . We point out that decays involving Bs mesons where the Ds 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 de- cays B ! D(�)Ds(2317)(Ds(2460)), if the Ds(2317) and Ds(2460) are interpreted as DK and DK molecules.
