Abstract:
A unified method of the investigation of enhancements of multi-channel T-matrix is proposed with use of the N/D method. The eigenvalue of coupled channel D-matrix is essentially used for the graphical investigation of resonances or cusp phenomena. There are two kinds of resonances which are clearly distinguished by the behaviours of trajectories of specified eigenvalue.
