Regge Trajectories For All Flavors

For a global analysis of mesonic resonances of all flavors, experimental data and phenomenological models are used to construct linear Regge trajectories. A satisfactory formula is found for the dependence of the intercept and slope on quark masses. We find agreement with data on charm production through exchange of our (spacelike) trajectories. Our results confirm the nonexistence of top meson and toponium.
