Addendum to triton and hypertriton binding energies calculated fromSU6quark-model baryon-baryon interactions

Abstract

Previously we calculated the binding energies of the triton and hypertriton, using an ${\mathrm{SU}}_{6}$ quark-model interaction obtained by 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 that is energy-independent and still preserves all the two-baryon data. The new binding energies are slightly smaller than the previous values. In particular the triton binding energy turns out to be 8.14 MeV with a charge-dependence correction of the two-nucleon force, 190 keV, being included. This indicates that the energy to be accounted for by three-body forces is about 350 keV.
