Description

In the E6-model of the superstring decays of Z0 boson with the nonconservation of lepton flavor (Z0→μe, μτ, eτ) induced by exchanges of scalar leptoquarks are considered. For the value of Yukawa coupling constant of leptoquarks with quarks and leptons ∼10-1 and the leptoquark mass M=200 GeV the branching ratio Br(Z0→μ+e-μ-e+)∼10-10 is obtained
