摘要We extend the chiral hadronic model (FST) with an inclusion of Λhyperon to investigate the properties of multi-Λhypernuclei. With such an effective hadronic model in the relativistic mean-field approximation, we accomplish the calculations with both the conventional strong Λ--Λ interaction and the weak Λ--Λ interaction determined from recent experiment. Our calculations indicate that not only the strong but also the weak Λ--Λ interaction provide tighter binding for multi-Λ hypernuclei than the ones with only nucleons. However the strong interaction generates a binding slightly tighter than the weak interaction.
