Abstract
We extend the theoretical framework used to describe the state as a molecular state of and make predictions for the and systems, finding that they lead to bound states only in the channel. Using input needed to describe the 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 system, while the system develops a strong cusp around the threshold.
