High-Energy Limit of Production Amplitudes

A simplified version of the Bali-Chew-Pignotti amplitude for multi-Regge-pole particle production is given using the recently developed projection-operator technique to construct many-particle states. This amplitude is generalized to a multi-Toller-pole expansion to avoid singularities which otherwise occur when any momentum-transfer variable goes to zero. It is shown how to determine the $M$ value of a Toller pole by measuring the distribution as a function of a Treiman-Yang angle.
