Abstract

Using fixed-angle amplitudes and the proper threshold and asymptotic conditions within the framework of the N/D formalism, the self-consistency of numerical solutions for the ϱ-meson parameters in ππ scattering is investigated. The results we obtain are unsatisfactory, showing yet again that a one-channel unitary calculation of the ϱ-meson, with no CDD poles, does not work.
