Resonance energy of the barKNN-piYN system
Abstract
The resonance energies of strange dibaryons are investigated with the use of the KNN-π Y N coupled-channels Faddeev equation. It is found that the pole positions of the predicted three-body amplitudes are significantly modified when the three-body coupled-channels dynamics is approximated, as is done in the literature, by the effective two-body KN interactions.
