Abstract

We show that the resonance-dominance approximation for the low-energy part of finite-energy sum rules for the C=+1, I=0 t-channel πN and KN elastic amplitudes reproduces correctly properties of the P′ trajectory and residue functions. The Pomeranchukon is fully accounted for by the low-energy background. The Gell-Mann ghost-eliminating mechanism is favored for the P′ trajectory.
