Both the measured jet energy distributions and the event orientation are reproduced by second order QCD. An alternative model with scalar gluons fails to describe the data

Search for leptoquarks in Z 0 decays

We have searched for direct leptoquark production in Z 0 decays from a scan of the Z 0 resonance, in the energy range 88.2 ≤ √s ≤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
