The operator approach to dual multiparticle theory

Alessandrini, Amati, Le Bellac, Olive.

The multi-partlc1e dual model is analyzed by making use of the operatorial approach. A new technique is introduced, which allows a comprehensive and simple treatment of operatorial manipulations, and is based on the underlying symmetry of the dual resonance model. The multiloop unitarization program is sketched, and explicit results for the one-loop amplitudes, including their renormalization, are given.
