On the resonance energy of the strange dibaryon
The three-body resonance energies of the strange dibaryon are studied with the View the MathML source 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 View the MathML source 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.
