Resonance energy of the barKNN-piYN system

Yoichi Ikeda, Toru Sato

英文摘要:

The resonance energies of strange dibaryons are investigated with the use of the \bar{K}NN-πY 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 \bar{K}N interactions.
