Molecular $$\Xi _{bc}$$ Ξbc states from meson–baryon interaction

Abstract

Abstract We 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.
