Description

Quark-model hyperon-nucleon and hyperon-hyperon interactions by the Kyoto-Niigata group are applied to the two-Λ plus α system in a three-cluster Faddeev formalism using two-cluster resonating-group method kernels. The model fss2 gives a reasonable two-Λ separation energy ΔBΛΛ=1.41 MeV, which is consistent with the recent empirical value, ΔBΛΛexp=1.01±0.20 MeV, deduced from the Nagara event. Some important effects that are not taken into account in the present calculation are discussed
