Abstract

Strange quarks produced in e+e--annihilation at the Z0-pole are very strongly polarized. To study to which extent this polarization is transferred to the observable hadrons would give interesting information on the hadronization mechanism. Γ-particles produced with relatively large x-values are expected to frequently contain an originally produced s-quark. We estimate that Γ-particles with x>0.3 should have a longitudinal polarization of about 30%.
