ππ interaction in the Born approximation of dual model with quantized slope of the Regge trajectories

The Born approximation for the ππ-interaction amplitude in the framework of the dual model with quantized slope of the Regge trajectories, proposed recently, is considered in the work. Partial widths of the low-lying resonances are calculated. Adler self-consistency condition is tested. The obtained energy spectrum and widths of the resonances are compared with the Lovelace-Shapiro model and with the Frampton model, as well as with the experimental data
