Abstract

Using the vector-exchange interaction in the local hidden gauge approach, which in the light quark sector generates the chiral Lagrangian, and has produced realistic results for Ωc,Ξc,Ξb\Omega_c, \Xi_c, \Xi_b and the hidden charm pentaquark states, we study the meson-baryon interactions in the coupled channels that lead to the Ξbb\Xi_{bb} and Ωbbb\Omega_{bbb} excited states of the molecular type. We obtain seven states of the Ξbb\Xi_{bb} type with energies between 1040810408 and 1086910869 MeV and one Ωbbb\Omega_{bbb} state at 1521215212 MeV.
