Regge Trajectories and Minima in Differential Cross Sections

Abstract

Attempts to fit [1] the earliest accurate measurements of high-energy cross sections, namely the total cross sections and diffraction peaks, by Regge poles have not been totally convincing because a number of high-spin trajectories contribute, and the theory involves a correspondingly large number of parameters. Some of the smaller cross sections now being measured, however, can be described in terms of only one or two trajectories, thus providing a cleaner test of Regge theory [2-4].
