Quark-model interactions for the complete baryon octet and their applications to few-baryon systems

摘要

Baryon-baryon interactions of the complete baryon octet (B-8) are investigated in a unified framework of the (3q)-(3q) resonating-group method, which employs the spin-flavor SU6 quark-model wave functions. Model parameters axe determined to reproduce properties of the nucleon-nucleon system and the low-energy cross section data for the hyperon-nucleon interaction. The characteristic features of the B8B8 interactions predicted by the most recent model fss2 axe reviewed. The nucleon-nucleon sector of this SU6 quark model is applied to calculate properties of the three-nucleon bound state. The calculated binding energy for H-3 is the closest to the experiment among many results obtained by detailed Faddeev calculations employing modern realistic nucleon-nucleon potentials.
