Abstract

Regge theory and some aspects of duality are used in order to parametrize the meson-baryon coupling constants, including first-order $S U_{3}$ -breaking effects. Five of the more relevant coupling constants are expressed in terms of three unknown constants, yielding two independent sum rules. An estimate of corrections due to $S U_{3}$ mass shifts is suggested.
