Phenomenology of the Triple-Regge Region

Abstract

A two-term triple-Regge formula, which follows from a simple theoretical picture of the single-particle inclusive cross section, is presented and studied. A comparison is made with recent data for $\mathrm{pp}\to p+\mathrm{anything}$, and $p{\pi }^{-}\to p+\mathrm{anything}$. The description of the data offered by this simple form is found to be remarkably good over a large region of phase space.
