Özet

In this work we study the decay of a B-c into a final state of J/psi DK mesons. We compute the KD invariant mass distribution considering that the heavy meson decays via weak interaction into a c (s) over bar quark pair, which hadronizes into final meson states. The D-s0*(2317) scalar resonance is dynamically generated by the interaction of the final state.We describe the interaction of mesons by a phenomenological Lagrangian. The parameters of the model are fine tuned in order to reproduce the mass of the scalar resonance, and then we predict the KD invariant mass distribution of the decay and the ratio of the processes B-c -> J/psi DK and B-c -> J/psi D-s0* (2317). This reaction proposed here has not been measured yet, and it can be sensitive to the nature of the D-s0*(2317).
