A measurement of the polarization of Lambda from Z decays
The polarization of $\Lambda$ from Z decays have been studied with the {\sc Aleph} apparatus. For the first time evidence of longitudinal polarization of $s$-quarks from Z decay is observed. It is shown to agree with the prediction from the standard model and the naive quark model within an uncertai...
