Research output: Contribution to journalArticlepeer-review


The three-body resonance energies of the strange dibaryon are studied with the over(K, ̄) N N - π Y N coupled-channels Faddeev equations. Our resonance energies are compared with those of an effective potential approach (EPA), where a coupling to the πYN channel is simulated by an effective over(K, ̄) N potential, and the spectator momentum in the πYN Green function is neglected. About a 30% reduction of the binding energies due to neglecting the spectator momentum in the πYN Green's function is observed.
