Abstract

In this talk, we investigate the molecular nature of the D∗ s0(2317)+ resonance in the weak decay of the Bc meson to J/ψDK. In this process, the heavy meson Bc first decays into the quark pair cs¯ via weak interaction and then the quark pair hadronizes into final meson states. The D∗ s0(2317)+ resonance is dynamically generated in the final state interaction. We describe this interaction using the chiral unitary approach. Finally, we compute the KD invariant mass distribution of the decay Bc → J/ψDK and we learn about the nature of the D∗ s0(2317)+.
