Scientific paper

Faddeev calculations of the triton and hypertriton and the G-matrix calculations of the octet-baryons are reexamined by using SU6 quark-model interactions derived from a resonating-group method of two baryon clusters. In contrast to the previous calculations employing the energy-dependent interaction kernel, we present new results using a renormalized interaction, which is now energy independent and reserves all the two-baryon data. The new binding energies of the triton and the hypertriton are slightly smaller than the previous values. The single-particle potentials of the octet baryons in nuclear matter are less attractive, but essentially the same as before.
