Investigation of Kn-πΣ interaction effects on Kˉpp system using Faddeev method

Coupled-channels Faddeev-Yacubovsky as well as AGS calculations of three-body, J π =0ˉ K(NN)I=1(I=1/2) quasibound state in the KNN- πΣ N system were performed in momentum space and the dependence of the three-body energy on the two-body KN- πΣ interaction was investigated.
