Abstract
The matrix method in the determinantal approximation is applied to the study of the phase shift using three coupled channels: , , and . The meson (also denoted by ) is an -wave resonance at a mass of about 730 MeV. Good agreement between the results of the model and experimental data is obtained for both the phase shift and the absorprion coefficient in the range from threshold to ∼600-MeV pion laboratory kinetic energy.
