Abstract ：Variational Monte Carlo calculations are carried out for ΛΛ 4 H to explore the possibility of its existence, using realistic NN , NNN , and phenomenological ΛN and ΛNN interactions. We also perform calculations using FGNNand 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 ΛΛ 4 H. Still the stability of ΛΛ 4 H remains an open question and this hypernuclear system has to be explored more theoretically.
