Effects of Unitarity on the Multiperipheral Model

Abstract

Two models are presented for which the full multiparticle $S$ matrix is unitary at high energies. The production mechanism is based on the multiperipheral model. It is shown that the elastic-scattering amplitude contains a new type of cut in the angular-momentum plane which is dynamical in origin. This unitarity cut plays a crucial role in enforcing the Froissart bound.
