Titel: Searches for lepton-flavour-violating decays of the Higgs boson in sqrt(s)=13 TeV pp collisions with the ATLAS detector

Kurzfassung: This Letter presents direct searches for lepton flavour violation in Higgs boson decays, Hâ†’eÏ„ and Hâ†’Î¼Ï„, performed with the ATLAS detector at the LHC. The searches are based on a data sample of proton-proton collisions at a centre-of-mass energy sqrt(s)=13 TeV, corresponding to an integrated luminosity of 36.1 fbâˆ’1. No significant excess is observed above the expected background from Standard Model processes. The observed (median expected) 95% confidence-level upper limits are 0.47% (0.34+0.13âˆ’0.10%) and 0.28% (0.37+0.14âˆ’0.10%) for Hâ†’eÏ„ and Hâ†’Î¼Ï„, respectively.
