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 _ΛΛ ⁴n bound state. Our results indicate that the _ΛΛ ⁴n is unbound, being just above threshold. We discuss the role played by the ¹ S ₀m nn repulsive term of the Yukawa-type Malfliet-Tjon interaction.
- baryon-baryon interactions,
- few-body systems
