The ΛΛ4n system

  • Using local central Yukawa-type Malfliet-Tjon interactions reproducing the low-energy parameters and phase shifts of the m nn system, and the latest updates of the m nΛ and ΛΛ Nijmegen ESC08c potentials, we study the possible existence of a ΛΛ4 n bound state. Our results indicate that the ΛΛ4 n is unbound, being just above threshold. We discuss the role played by the 1S0 m nn repulsive term of the Yukawa-type Malfliet-Tjon interaction.

The ΛΛ4n system

Abstract: Using local central Yukawa-type Malfliet-Tjon interactions reproducing the low-energy parameters and phase shifts of the m nn system, and the latest updates of the m nΛ and ΛΛ Nijmegen ESC08c potentials, we study the possible existence of a ΛΛ4 n bound state. Our results indicate that the ΛΛ4 n is unbound, being just above threshold. We discuss the role played by the 1S0 m nn repulsive term of the Yukawa-type Malfliet-Tjon interaction.
