Molecular states with bottom mesons and multistrange baryons systems

Abstract

We investigate molecular states formed by bottom mesons and multistrange baryons from both octet and decuplet flavor representations, using the local hidden gauge approach combined with coupled-channel Bethe-Salpeter equations. Focusing on strangeness sectors S=1S = -1 to 4-4, we predict several bound states in the S=1,I=1/2, 3/2S=-1, I=1/2,~3/2 and S=2,I=0S=-2, I=0 sectors. No bound states are found in other isospin channels, where the interaction is repulsive, nor in higher strangeness sectors. The binding energies are analyzed under different values of the cutoff regularization parameters, providing estimates of theoretical uncertainties. This study provides concrete predictions to support future experimental investigations and improve understanding of heavy-flavor multistrange exotic hadrons.
