Search for lepton flavour violation in Z<sup>0</sup> decays

We have searched for lepton flavour violation in Z<sup>0</sup> boson decays into lepton pairs, Z<sup>0</sup>→μτ, Z<sup>0</sup>→eτ, and Z<sup>0</sup>→eμ. The data sample is based on an integrated luminosity of 10.4 pb<sup>-1</sup> correspond...

Descrição
Resumo:We have searched for lepton flavour violation in Z<sup>0</sup> boson decays into lepton pairs, Z<sup>0</sup>→μτ, Z<sup>0</sup>→eτ, and Z<sup>0</sup>→eμ. The data sample is based on an integrated luminosity of 10.4 pb<sup>-1</sup> corresponding to 370 000 Z<sup>0</sup>’s produced. We obtain upper limits on the branching ratios of 4.8 X 10<sup>-5</sup> for the μτ 3.4 X 10<sup>-5</sup> for the eτ and 2.4 X 10<sup>-5</sup> for the eμ decay modes at the 95% confidence level.
