摘要：

We have searched for direct leptoquark production in Z0 decays from a scan of the Z0 resonance, in the energy range 88.2 less-than-or-equal-to squar-root s less-than-or-equal-to 94.2 GeV, using 5.2 pb-1 of data. We exclude the existence of scalar leptoquarks with masses less than 41 to 44 GeV, depending on the charge assignments, at the 95% confidence level.
