Abstract

We scrutinize hadronic Regge trajectories in the framework of two different models - string and potential. Our. results are compared with a broad spectrum of existing theoretical quark models and experimental data from PDG98. It was recognized that Regge trajectories for mesons and baryons deviate from straight and parallel fines in general in the current resonance regionboth experimentally and theoretically. They very often have appreciable curvature, which is flavor dependent. For a set of baryon Regge trajectories this fact is well described in the considered potential model. The standardstring models predict linear trajectories at high angular momenta J with some form of nonlinearity at low J. This model is also adequate for the majority of orbitally excited hadron states.
