From PKoppenburg on Twitter: Nice. The @ATLASexperiment reports limits on lepton-flavour violating Z boson decays, Z→τ⁺μ⁻ and Z→τ⁺e⁻. First time the LHC improves on best limits from LEP dating more than 20 years ago. The article is dedicated to Olya Igonkina. https://twitter.com/PKoppenburg/status/1313738392979546115/photo/1
