Regge Trajectories For All Flavors

Abstract

Based on available data for mesonic resonances of light, medium and heavy flavors, we have performed a global analysis to construct the corresponding linear Regge trajectories. These have been supplemented by results from various phenomenological models presented in the literature. A satisfactory formula is found for the dependence of the intercept and the slope on quark masses. We find reasonable agreement with data on production of charmed hadrons through exchange of our charmed trajectories in the space-like region. When applied to mesons containing the top quark, our results suggest the impossibility of their formation as evidenced by other independent analyses.
