Pomeranchuk Trajectory and Its Relation to Low-Energy Scattering Amplitudes
Abstract
While "ordinary" Regge trajectories can be bootstrapped using the resonance approximation to finite-energy sum rules, we suggest that the Pomeranchuk trajectory is mostly built from the nonresonating background at low energies. This hypothesis (a) explains the constancy of KN and NN total cross-sections (in contrast to K¯N and N¯N over a wide energy range; (b) predicts many other interesting relations which are experimentally satisfied; and (c) leads to no obvious inconsistencies.
