Abstract
Two superconvergent dispersion relations are proposed for the sum of three charge-conjugated meson-nucleon forward scattering amplitudes. These two sum rules can be evaluated exactly without using an approximation of saturation. They are obtained under the assumption that asymptotically the pole couples to the pion and kaon universally. We use them here for a determination of the kaon-nucleon coupling constants.
