Hypernuclear physics, a brief past and bright future

“…Furthermore, he attributes 100 keV of the binding to the effective three-body force. Earlier calculations [43] using the Juelich potential models [36][37][38] were not in such good agreement with the experimental A separation energy.…”

“…The shorter range Kexchange potential does admit a tensor-force component, but it is largely cancelled by that from K*-exchange. Thus, tensor-force effects in the NA interaction are expected to be smaller than those in the NN interaction [33][34][35][36][37][38][39]. On the other hand, explicit NA -NE (octet-octet) mixing in the hyperon-nucleon sector appears to play a much larger role in hypernuclear physics than does NN -NA (octet-decuplet) mixing in the nonstrange sector.…”
