Spin effects in large-angle meson-baryon scattering

We remark that recent data on large-angle meson-baryon scattering at high energies are nicely accounted for by the massive-quark model and quark-geometrodynamic model developed a few years ago. In particular we reproduce the correct size and rho-alignment properties of the reaction ..pi../sup -/p..-->..rho/sup -/p. We also predict a very small scattering cross section for the reaction ..pi..N..--> pi delta... .AE
