Abstract

We propose that Mueller-Regge theory be tested in the triple-Regge region by taking ratios of inclusive cross sections which receive contributions from similar trajectories, so that normalized triple-Regge vertices are not needed. The remaining residues and trajectory functions are then determined using phenomenological fits to two-body differential cross sections. We consider three classes of fragmentations, involving baryon exchange, hypercharge exchange, and exotic exchange, respectively, and compare our predictions with available experimental data. Reasonable agreement with experiment is found in all cases.
