C-parity and Regge Intercepts

TL;DR

This paper derives constraints on the intercepts of Regge trajectories with definite C-parity, linking their properties to the nature of forces in elastic scattering and particle interactions.

Contribution

It introduces a heuristic argument connecting C-parity of Regge exchanges to the attractive or repulsive forces in hadron scattering, providing new constraints on Regge intercepts.

Findings

C-even exchanges correspond to attractive forces in elastic scattering

C-odd exchanges relate to attractive or repulsive forces depending on particle type

Constraints on Regge intercepts based on C-parity are established

Abstract

In this work, we obtain constraints on the intercepts of the Regge pole tra jectories (which we believe to have definite C-parity) based on the heuristic argument that C-even exchanges correspond to attractive forces between hadrons undergo ing 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.
