We have searched for lepton flavour violation in Z0 boson decays into lepton pairs, Z0 --> mu-tau, Z0 --> e-tau, and Z0 --> e-mu. The data sample is based on an integrated luminosity of 10.4 pb-1 corresponding to 370 000 Z0's produced. We obtain upper limits on the branching ratios of 4.8 x 10(-5) for the mu-tau, 3.4 x 10(-5) for the e-tau and 2.4 x 10(-5) for the e-mu decay modes at the 95% confidence level.

Abstract
We have searched for lepton flavour violation in Z0 boson decays into lepton pairs, Z0 --> mu-tau, Z0 --> e-tau, and Z0 --> e-mu. The data sample is based on an integrated luminosity of 10.4 pb-1 corresponding to 370 000 Z0's produced. We obtain upper limits on the branching ratios of 4.8 x 10(-5) for the mu-tau, 3.4 x 10(-5) for the e-tau and 2.4 x 10(-5) for the e-mu decay modes at the 95% confidence level.File in questo prodotto:
