Analysis of Heavy Hyper hydrogen _Λ~6H

摘要

We have revisited the possible existence and the binding mechanism of heavy hyperhydrogen _Λ~6H. This A hypernucleus is enriched in information about Λ hypernuclear dynamics which would shed a light on significant role of coherent Λ-Σ coupling effect in neutron-rich nuclear medium, discussed by the authors. Recently, reports on an experimental evidence of with theoretical comparison have appeared, wherein the significance of the coherent coupling in _Λ~6H has been criticized. In this report, we are revising our previous work and give further theoretical analysis to confirm the influence of the ΛN-ΣN coupling effect in the binding mechanism of _Λ~6H.
