Systematic study of baryon-baryon interactions in singly bottomed systems

In this work, we systematically investigate the baryon-baryon interactions in singly bottomed dibaryon systems within the chiral quark model and search for possible bound states. By exploring the baryon-baryon interaction, we find that low-isospin channels tend to generate deeper attractive interactions and are prone to form bound states. We also find that decuplet-decuplet systems tend to show stronger attraction and support a larger number of bound states, whereas octet-octet systems generally exhibit weaker attraction and fewer bound solutions. The binding behavior of octet-decuplet systems generall lies between these two cases. Several bound states are obtained, which are ΔΣb^* with IJ=1/20, 1/21, 1/22, 1/23, and 3/23, the ΔΣb with IJ=1/21, 1/22, 3/21, and 3/22, the NΣb^* with IJ=1/22, the ΣΣb with $IJ=00$, $01$, and $11$, the ΣΣb^* with $IJ=01$ and $02$, the Σ^*Σb with $IJ=01$ and $02$, and the Σ^*Σb^* with $IJ=00$, $01$, $02$, $03$, and $13$. Further investigations of the corresponding scattering processes are still required to determine whether these bound-state candidates can be identified. These states deserve further experimental investigation.
