In order to write dispersion relations for the T = 1, J = 0 amplitudes, we study the complex singularities that are present in the Born amplitude for the production process. We use the N/D coupled channels method for the helicity partial wave amplitudes and write the explicit equations for the T = 1, J = 0 amplitudes taking into account, through a simplified model, the contributions of the complex singularities.75 ppengCopyright is held by the author, unless otherwise indicated.
