Hadronic amplitudes in the dual model with quantized slope of the Regge trajectories

Interaction amplitudes for an arbitrary number of pions are constructed in the Born approximation of the dual model with quantized slope of the Regge trajectories. The dual vertex operators of the Bardakci-Halpern type and the propagators leading to the quantization of the Reggeon slope were used. The internal degrees of freedom in the model permit a natural introduction of nucleons, kaons and hyperons. Even the predictions of the Born approximation for the hadronic spectrum are in a reasonable agreement with the experimental data
