Abstract
We compare the data on K/sup +/-p elastic, KN charge-exchange, and ..pi../sup -/p ..-->.. eta/sup 0/n scattering with several classes of models. We show that the simple Regge-pole model is surprisingly good except for certain discrepancies with the data in and near the forward direction. It is found that if we add high-energy terms of a quadratic form in logs to all exchanges while at the same time imposing certain desirable restrictions (for example exchange degeneracy) on the Regge-pole parameters, an accurate description of the data can be obtained. Polarization predictions at high energy clearly distinguish between the different types of model, and KN charge-exchange and eta/sup 0/ production are shown to offer the best test of the existence of these unconventional effects near t = 0.
