Abstract

The decays of the Z{sup 0}-bosons with lepton flavour violation (Z{sup 0} {yields} {mu}e, {mu}{tau}, e{tau}) are studied in the framework of superstring-inspired E{sub 6} model. For Yukawa coupling {lambda} leptoquark with quarks and leptons {approx} 10{sup -1} and for leptoquarks mass M=200 GeV there are Br(Z{sup 0} {yields} {mu}{sup +}e{sup -} + {mu}{sup -}e{sup +}) {approx} 10{sup -10} is obtained. 9 refs.; 5 figs.
