Dynamics of hyperon--antihyperon production

Abstract

The dynamics of the strangeness-exchange reactions antiproton-proton to AntiLambda-Lambda, AntiLambda-Sigma or AntiSigma-Sigma is discussed, either at the hadron level, in terms of strange-meson exchange, or at the quark level, in terms of quark--antiquark creation or annihilation.
