Abstract

A three channelN/D model of π π scattering, the pion form factor, ande + e −→4π cross sections is investigated. The dispersion relation subtraction constants and other parameters are chosen to optimize resonances are generated, the ρ(770) and ρ(1600), and that there is no ρ(1250) resonant state.
