Abstract
A model for pseudoscalar-meson-baryon and pseudoscalar-meson-baryon-resonance hpyercharge- and charge-exchange reactions at high energies is proposed, based on an octet of pairs of opposite-signature Regge poles. The model may be considered as an extension of the charge-exchange reaction model for used by Phillips and Rarita, incorporating symmetry and exchange degeneracy. In addition, the universality hypothesis is employed to extend the model to production. The model thus extended contains only a few parameters (essentially only 2) and agrees with all available high-energy, small-momentum-transfer data on these reactions. The energy dependences (involving no free parameters) are very good; the universality hypothesis is satisfied within narrow experimental bounds, and -symmetric normalizations are within a factor of 2 for most cross sections at high energy.
