Abstract
A detailed quark-model study of the ΛN-ΣN(I=1/2) system is given in a coupled-channel formulation of the RGM-F which has been recently introduced to achieve a unified understanding of the NN and hyperon-nucleon interaction. It is found that the effect of the ΛN-ΣN transition potential is strongly enhanced in the threshold region through important contributions of the non-central components. The antisymmetric LS(−) force, which is characteristically strong in the quark model with the full Fermi-Breit interaction, reproduces the prominent bump structure in the ΛN total scattering cross sections at energies slightly below the ΣN threshold.Keywords
