Variational Monte Carlo Study of ΛΛ4H

Abstract

Variational Monte Carlo calculations are carried out for ΛΛ4H to explore the possibility of its existence, using realistic NN, NNN, and phenomenological ΛN and ΛNN interactions. We also perform calculations using FGNN and NSC97 ΛN potentials, and demonstrate the effect of the exchange part of the two-body ΛN interaction and three-body ΛNN interaction on the binding energy of ΛΛ4H. Still the stability of ΛΛ4H remains an open question and this hypernuclear system has to be explored more theoretically.
