Triton and hypertriton binding energies with SU[sub 6] quark-model baryon-baryon interactions

Abstract

Previously we calculated the binding energies of the triton and hypertriton, using an SU6 quark‐model interaction which is obtained by a resonating‐group method for 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 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.
