Description

Using local central Yukawa-type Malfliet-Tjon interactions reproducing the low-energy parameters and phase shifts of the nn system, and the latest updates of the nΛ and ΛΛ Nijmegen ESC08c potentials, we study the possible existence of a ΛΛ4n bound state. Our results indicate that the ΛΛ4n is unbound, being just above threshold. We discuss the role played by the 1S0 nn repulsive term of the Yukawa-type Malfliet-Tjon interaction. (authors)
