Structure, formation, and decay of system by Faddeev-AGS calculations

Abstract

Abstract The Faddeev AGS equations for the coupled-channels system with quantum numbers I= 1/2 and S= 0 are solved. Using separable potentials for the interaction, we calculate the transition probability for the reaction. The possibility to observe the trace of the quasi-bound state in mass spectra was studied. Various types of chiral-based and phenomenological potentials are used to describe the interaction. Finally, we show that we can observe the signature of the quasi-bound state in the mass spectra, as well as the trace of branch points in the observables.
