Regge-Pole Models for High-EnergyπN,KN, andK¯NScattering

It is shown that $\pi N$, $\mathrm{KN}$, and $\overline{K}N$ elastic-scattering and charge-exchange data at high energy and small momentum transfer can be well fitted by assuming that the amplitudes are dominated by a few Regge poles in the crossed channel. The constraints imposed by the factorization principle are included. Unitary symmetry ($S{U}_3$) is approximately satisfied. Sample predictions of $\pi p$ polarization and $K^{+}+n\to K^0+p$ charge exchange are made.
