Abstract

A self-consistent calculation of some features of the low-energy pion resonances is performed by a "boot-strap" method which preserves unitarity and the analytic properties of scattering amplitudes and satisfies crossing symmetry approximately. The interaction of two-pion states with pion-omega meson states is decisive for the properties of the ρ meson. Values of the ρ-meson mass and width and the ω-meson width are obtained in terms of the pion and ω-meson masses and are in fair agreement with experiment.
