An Equation Incorporating Crossing Symmetry, Regge Asymptotic Behaviour, and Two-body Unitarity

Abstract

An explicitly crossing. symmetric generalization of Kadyshevsky's quasi. potential equation is proposed. The equation has the two.body unitarity cuts in all three channels. Applied to a particular continuation of the Veneziano amplitude off the energy-momentum shell, it produces an amplitude with Regge asymptotic behaviour.
