Abstract
Motivated by the recent finding of five states by the LHCb collaboration, and the successful reproduction of three of them in a recent approach searching for molecular states of meson-baryon with the quantum numbers of , we extend these ideas and make predictions for the interaction of meson-baryon in the beauty sector, searching for poles in the scattering matrix that correspond to physical states. We find several states: two states with masses 6405~MeV and 6465~MeV for ; two more states with masses 6427~MeV and 6665~MeV for ; and three states between 6500 and 6820~MeV, degenerate with , stemming from the interaction of vector-baryon in the beauty sector.
