Search for lepton flavour violation in Z boson decays — •David Brunner, Jordy Degens, Peter Fackeldey, Olena Hlushchenko, Wolfgang Lohmann, Johannes Merz, Thomas Müller, Alexander Nehrkorn, Claudia Pistone, Dennis Roy, Hale Sert, Achim Stahl, and Dominik Wolfschläger — Physics Institute III B, RWTH Aachen University

In interactions of charged leptons only processes conserving the lepton flavour are observed. Since there is no known symmetry requiring this, a model independent search for Z bosons decays violating lepton flavour conservation is done in final states with electrons, muons and tau-leptons.

For this purpose a cut based analysis strategy is choosen. Bayesian statistics are used to calculate exclusion limits on the braching ratios of Z decays violating lepton flavour conversation. This analysis is done with the CMS data of 2016 with a center of mass energy of √s = 13TeV and an integrated luminosity of L = 35.9fb⁻¹.
