Resumen
We have solved the Faddeev equations for ηd elastic scattering using realistic separable interactions for the NN and coupled ηN-πN subsystems. We found that including explicitly the pion channel in the integral equations drastically reduces the attraction that is present in the system. As a consequence, the existence of a ηNN quasibound state is excluded by the modern ηN amplitude analysis.
