s-Shell Lambda -Hypernuclei Taking into Account Lambda N- capital sigma N Coupling Explicitly with TOSM

The Lambda N- capital sigma N coupling is one of the open questions in strangeness physics. We studied the Lambda N- capital sigma N 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...

Summary:The Lambda N- capital sigma N coupling is one of the open questions in strangeness physics. We studied the Lambda N- capital sigma N 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 Lambda -hypernuclei, sub( ) Lambda super(4)H and sub( ) Lambda super(5)He, and investigate the roles of the Lambda N- capital sigma N coupling interaction in those hypernuclei.
