AbstractAbstract
[en] It is found that the suppression due to two-body ΛN-ΣN coupling solves the overbinding problem in Λ5He but it causes a severe underbinding in the four-body systems. The shortage of this binding is overcome by introducing the Λ-Σ coupling explicitly which is equivalent to the ΛNN three-body force. This three-body force becomes strong in the 0+ state of Λ4H and Λ4He according to the coherent enhancement. In the strangeness -2 sector there is a possibility that the lightest double-Λ hypernucleus ΛΛ4H is abundantly populated via an exotic atom by stopping Ξ- on 4He. An excited state with strangeness halo appears in a double-strangeness five-body system. (author)
