Abstract

A new cascade model of hardron fragmentation is proposed, which satisfies the following properties of the multiperipheral model: i) symmetry under rapidity reversal; ii) strong cut-off in momentum transfer squared; iii) physical multi-Regge and triple-Regge limits. The model is applied to the dual cut pomeron. Improvements over the dual parton models are pointed out. The possibility of treating higher orders of the reggeon field theory, such as diffraction, exchange of several cut pomerons and enhanced diagrams, is discussed.
