Abstract

Many extensions of the standard model, e.g., certain composite models and some superstring-"inspired" E6 models, contain new scalar matter fields which couple to both quarks and leptons, i.e., leptoquarks. We consider leptonic flavor-changing decays of the Z0, e.g., Z0+-, due to one-loop diagrams involving such leptoquarks. We find branching ratios which are at most 10-7, even assuming generous values for unknown Yukawa couplings.
