چکیده
We extend the theoretical framework used of describe $T_{cc}$ state as a molecular $D^* D$ and make predictions for $D^*D^*$ $D^*_s D^*$ systems, finding that they lead to bound states only in $J^P=1^+$ channel. Using input needed state, basically one parameter regularize loops Bethe-Salpeter equation, we find with bindings order MeV similar widths system, while $D^{*}_s D^{*}$ system develops strong cusp around threshold.
