Summary
A model for the Λ-N and Λ-Λ potentials is presented, based on the exchange of η, K, ω, K* and a phenomenological scalar meson S. The S coupling is adjusted empirically, but other couplings are fixed by unitary symmetry and by comparison with theN-N problem. The model gives a reasonable fit to most of the data.
Riassunto
Per i potenziali A-N e Λ-Λ si presenta un modello basato sullo scambiodi η. K, ω, K* e di un mesono scalare fenomenologicoS. L’accoppiamento dell’S si aggiusta empiricamente, ma gli altri accoppiamenti si fissano in base alla sinimetria unitaria e per confronto col problemaN-N. II modello da un ragionevole accordo con la maggioranza dei dati.
