Theory of High-Energy Polarizations

Abstract

Using Regge poles with $\mathrm{SU}\left(3\right)\mathrm{}$ and exchange degeneracy, a theory of all experimentally accessible polarizations arising from pole-pole interferences is presented for pseudoscalar-baryon and baryon-baryon scattering and exchange reactions with all parameters (except for one sign) determined from differential cross-section data. All available data on $\pi p$, $\mathrm{Kp}$, $\overline{p}p$, and $\mathrm{pp}$ elastic and ${\pi }^{+}p\to K^{+}{\Sigma }^{+}$ polarizations are compared with this theory at the highest available energies, and many predictions are presented.
