Description
We study the Bc- �→ π- J/ψω and Bc- �→ π- D* anti D* reactions and show that they are related by the presence of two resonances, the X(3940) and X(3930), that are of molecular nature and couple most strongly to D* anti D*, but also to J/ψω. Because of that, in the J/ψω mass distribution we find a cusp with large strength at the D* anti D* threshold and predict the ratio of strengths between the peak of the cusp and the maximum of the D* anti D* distribution close to D* anti D* threshold, which are distinct features of the molecular nature of these two resonances.
