| Abstract: | The explicit ΛN ? ΣN coupling in s-shell hypernuclei is studied by using the tensor-optimized shell model. We show the obtained results of s-shell hypernuclei, ${_{Lambda}^{4}{rm H}}$ and ${_{Lambda}^{5}{rm He}}$ , and investigate the roles of the ΛN ? ΣN coupling interaction in those hypernuclei. |
