Strange dibaryon and $$\bar K$$NN- πΣN coupled channel equation

\( \bar K \) NN three body resonance has been studied by the \( \bar K \) NN — πΣN coupled channel Faddeev equation. The S-matrix pole has been investigated using the scattering amplitude on the unphysical Riemann sheet. As a result we found a three-body resonance of the strange dibaryon system with a binding energy B ∼ 76MeV and a width Г ∼ 54MeV.
