Perturbative recipe for quark-gluon theories and some of its applications

Abstract

We explore the possibility that the intercepts of the nonstrange meson and baryon Regge trajectories are simply related to quark spin. This possibility arises if one adopts a multiperipheral bootstrap for these (ordinary) trajectories and also a perturbative recipe relating a process with a given number of particles to quark-gluon diagrams. The possible implication of the scheme for the Pomeron are also discussed.
