${\Xi }_{bb}$ and ${\Omega }_{bbb}$ molecular states

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 ${\Omega }_c,{\Xi }_c,{\Xi }_b$ and the hidden charm pentaquark states, we study the meson-baryon interactions in the coupled channels that lead to the ${\Xi }_{bb}$ and ${\Omega }_{bbb}$ excited states of the molecular type. We obtain seven states of the ${\Xi }_{bb}$ type with energies between $10408$ and $10869$ MeV and one ${\Omega }_{bbb}$ state at $15212$ MeV.
