Abstract: We make a detailed study of the longitudinal polarization of hyperons andanti-hyperons in semi-inclusive deep-inelastic lepton-nucleon scattering.
Wepresent the numerical results for spin transfer in quark fragmentationprocesses, analyze the possible origins for a difference between thepolarization for hyperon and that for the corresponding anti-hyperon.
Wepresent the results obtained in the case that there is no asymmetry between seaand anti-sea distribution in nucleon as well as those obtained when such anasymmetry is taken into account.
We compare the results with the available datasuch as those from COMPASS and make predictions for future experimentsincluding those at even higher energies such as at eRHIC.
