Abstract

The ΛN-ΣN coupling is one of the open questions in strangeness physics. We studied the ΛN-ΣN coupling explicitly in light s-shell hypernuclei using Tensor Optimized Shell Model, which is ab initio like approach starting from the realistic interaction. We show the obtained results of s-shell Λ-hypernuclei, _Λ⁴H and _Λ⁵He, and investigate the roles of the ΛN-ΣN coupling interaction in those hypernuclei.
