AbstractWe systematically study the hadron longitudinal polarizations of the octet baryons at large z from quark fragmentations in e(+)e(-)-annihilation, the polarized charged lepton deep inelastic scattering (DIS) process, and the neutrino (antineutrino) DIS process, based on predictions of quark distributions for the octet baryons in the SU(6) quark-spectator-diquark model and a perturbative QCD based counting rule analysis. We show that the e(+)e(-) annihilation and the polarized charged lepton DIS process are able to distinguish between the two different predictions of the hyperon polarizations. We also find that the neutrino-antineutrino DIS process is ideal in order to study both the valence content of the hyperons and the antiquark to hyper-on (quark to antihyperon) fragmentations, which might be related to the sea content of hyperons.
