Abstract.

We study the \( B^{+} \rightarrow J/\psi \omega K^{+}\) reaction, and show that it is driven by the presence of two resonances, the X(3940) and X(3930), that are of molecular nature and couple most strongly to \( D^{\ast} \bar{D}^{\ast}\), but also to \( J/\psi\omega\). Because of that, in the \( J/\psi\omega\) mass distribution we find a peak related to the excitation of the resonances and a cusp with large strength at the \( D^{\ast} \bar{D}^{\ast}\) threshold.
