Abstract

Motivated by the recent finding of five Ωc\Omega_c 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 Ωc\Omega_c, 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 Ωb\Omega_b states: two states with masses 6405~MeV and 6465~MeV for JP=12J^P= \frac{1}{2}^-; two more states with masses 6427~MeV and 6665~MeV for 32\frac{3}{2}^-; and three states between 6500 and 6820~MeV, degenerate with JP=12,32J^P=\frac{1}{2}^-,\,\frac{3}{2}^-, stemming from the interaction of vector-baryon in the beauty sector.
