ROLE OF ɅN AND ɅNN INTERACTION PARAMETERS ON BINDING ENERGY OF AND

Bhupali Sharma

Abstract


Variational Monte Carlo study has been done for  the two hypernuclear systems       and           for calculation of binding energies. For the two hypernuclear systems under study, different potential models have been used for the interactions involved in these hypernuclear systems. ArgonneV18  NN, Urbana IX NNN and phenomenological ɅN and ɅNN potentials have been used in our study. Our potential models are based on our previous studies on different double lambda hypernuclear systems. From our results, hyperon-nucleon parameters  ie.  two-body ɅN parameter and three-body ɅNN parameters are  found to be important for binding the hypernuclear systems under study. With reduction in the values of ɅNN interaction parameters used in earlier works , there is significant difference in the values of binding energy of         and        . Also, ɅN interaction parameters are also found to play important role in binding.
