Strange dibaryon and KNN-pi Sigma N coupled channel equation
Yoichi Ikeda, Toru Sato
Abstract
KNN three body resonance has been studied by KNN-pi Sigma N coupled channel Faddeev equation. The S-matrix pole has been investigated using the analytically continued scattering amplitude on the unphysical Riemann sheet. As a result we found a three-body resonance of strange dibaryon system with the binding energy and width B=76MeV and Γ=54MeV.
