Abstract
The structure of the T = 1 iso-triplet hypernuclei, Λ7He, Λ7Li and Λ7Be within the framework of an α + Λ + N + N four-body cluster model is studied. A phenomenological ΛN charge symmetry breaking (CSB) interaction is introduced. The Λ binding energy of the ground state in Λ7He is predicted to be 5.16 (5.36) MeV with(without) the CSB interaction. The five-body cluster model calculation of α α n Λ Λ for Λ Λ11Be, which has been observed as Hida event, is performed. The calculated BΛ Λ is 18.23 MeV, which is less bound by about 2 MeV than the experimental data. The structure calculation in Ξ-7Li and Ξ-10Li are performed within the framework of α Ξ- n n and α α Ξ- n four-body model. Ξ-7Li and Ξ-10Li are predicted to have bound states. We propose to observe the bound states in future (K-, K+) experiments using 7Li and 10B targets in addition to the standard 12C target.
