LU TP 92-29 December 1992 Lambda-polarization in e+e-annihilation at the Z^0-pole G\"osta Gustafson Jari H\"akkinen Strange quarks produced in e+e^-annihilation at the Z^0-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. Lambda-particles produced with relatively large x-values are expected to frequently contain an originally produced s-quark. We estimate that Lambda-particles with x>0.3 should have a longitudinal polarization of about 30%.
