Crossing-symmetric regge-pole model for π-π scattering

An interference model of -x-r scattering is constructed which possesses linearly rising trajectories, Regge behaviour, resonances in all channels and is crossing symmetric. The model satisfies the Adler condition and predicts the Weinberg scattering lengths to within 10%. The calculated partial widths of the resonances associated with the leading trajectory are in reasonable agreement with experiment.
