The following three decays are considered: H → eτ, H → µτ, and Z → µτ. The searches are based on the data sample of proton–proton collisions collected by the ATLAS detector corresponding to an integrated luminosity of 20.3 fb−1 at a centre-of-mass energy of √s = 8 TeV. No significant excess is observed, and upper limits on the lepton-flavour-violating branching ratios are set at the 95% confidence level: Br(H → eτ) < 1.04%, Br(H → µτ) < 1.43%, and Br(Z → µτ) < 1.69 × 10−5.en-USJournal Article2023-06-3010.1140/epjc/s10052-017-4624-0
