AbstractWe have studied the meson–baryon interaction in coupled channels with the same quantum numbers of $$\Xi _{bc}$$Ξbc. The interaction is attractive in some channels and of sufficient intensity to lead to bound states or resonances. We use a model describing the meson–baryon interaction based on an extrapolation of the local hidden gauge approach to the heavy sector, which has been successfully used in predicting $$\Omega _c$$Ωc and hidden charm states. We obtain many states, some of them narrow or with zero width, as a consequence of the interaction, which qualify as molecular states in those channels. The success in related sectors of the picture used should encourage the experimental search for such states.

Baryon Interaction

We investigate a symmetrized ansatz for the dibaryon system in the Skyrme model. The ansatz obeys the same reflection symmetry that is observed in the complete, static numerical solution for the B=2 sector. The baryon-baryon potential between two skyrmions is calculated as a function of the separation distance. As a check on our numerics and on the general validity of the procedure, we verify that the baryon number is equal to two and is independent of the separation distance. This symmetrized ansatz does not yield attraction in the baryon-baryon interaction.
