Effective baryon-baryon potentials in the quark delocalization and color screening model Original Research Article

The quark delocalization and color screening model is used for a systematic study of the effective potential between baryons in the u, d and s sector. The model is constrained by the properties of baryons and N-N scattering. The effective potentials for the N-N (IJ = 01, 10, 11, 00) channels and the N-Λ and N-Σ (View the MathML source) channels fit the N-N, N-Λ and N-Σ scattering data reasonably well. This model predicts: there are rather strong effective attractions between some decuplet-baryons; the effective attractions between octet-baryons are usually weak; and the attractions between decuplet- and octet-baryons lie in between.
