s-Channel Picture for Reggeon Couplings to Baryons

Abstract
A simple s-channel picture of the dominant non-Pomeranchuk contributions to the A amplitude in 0 meson-12+-baryon scattering leads to (i) a physical interpretation of the F parameter in Reggeon and tadpole couplings to baryons, and (ii) selection rules for baryon couplings to mesons and baryons.
