Study on the Structure of Hypernuclei ΛΛ5H,ΛΛ5He,ΛΛ4He and ΛΛ4H

  • In this paper, double Λ binding energies BΛΛ s of ΛΛ5He(ΛΛ5H), AA4He and ΛΛ4H are calculated with the help of few-body models. The results show that stable binding state for ΛΛ5H or ΛΛ5He exists definitely with BΛΛ(ΛΛ5H)=6.75MeV and BΛΛ(ΛΛ5He)=7.67MeV,respectively. As to ΛΛ4He and ΛΛ4H, preliminary results indicate that ΛΛ4H is unstable against decaying into Λ+Λ3H, and ΛΛ4He has no binding state.

Abstract: In this paper, double Λ binding energies BΛΛ s of ΛΛ5He(ΛΛ5H), AA4He and ΛΛ4H are calculated with the help of few-body models. The results show that stable binding state for ΛΛ5H or ΛΛ5He exists definitely with BΛΛ(ΛΛ5H)=6.75MeV and BΛΛ(ΛΛ5He)=7.67MeV,respectively. As to ΛΛ4He and ΛΛ4H, preliminary results indicate that ΛΛ4H is unstable against decaying into Λ+Λ3H, and ΛΛ4He has no binding state.
