Abstract: (Springer)
Dispersion relations and finite-energy sum rules (FESR’s) on hyperbolas in the real Mandelstam plane which are asymptotic to lines of fixeds andu together with an ellipse on whichs andu are complex are derived. These FESR’s on hyperbolas are applied to backward and near-backward πN scattering and are used to extract information about the first eight partial-wave amplitudes for the reactionNN- → ππ in the article which follows this.- backscatter
