C-parity and Regge Intercepts

Abstract

In this work, we obtain constraints on the intercepts of the leading Regge pole trajectories -- Pomeron and Odderon -- implies by C-parity and based on the heuristic argument that C-even exchanges correspond to attractive forces between hadrons undergoing elastic scattering, and C-odd exchanges correspond to attractive forces in the case of particle-antiparticle scattering and repulsive forces in the case of particle-particle scattering. In addition, the case of degenerate (without definite C-parity) trajectories is also considered.
