| Popis: | We extend the theoretical framework used to describe the Tcc state as a molecular state of D∗D and make predictions for the D∗D∗ and Ds∗D∗ systems, finding that they lead to bound states only in the JP=1+ channel. Using input needed to describe the Tcc state, basically one parameter to regularize the loops of the Bethe-Salpeter equation, we find bound states with bindings of the order of MeV and similar widths for the D∗D∗ system, while the Ds∗D∗ system develops a strong cusp around the threshold. |
