Binding energies of hypernuclei and Λ‐nuclear interactions

Variational calculations indicate that a reasonable description of Λp scattering and of Λ separation energies can be obtained in terms of ΛN plus dispersive and TPE ΛNN forces. Results for the ΛΛ interaction and for _ΛΛ⁶He obtained from an analysis of ¹⁰_ΛΛBe are discussed. Coulomb and ΛN charge symmetry breaking effects in the A=4 hypernuclei are discussed.
