dc.description.abstractDirect searches for lepton flavor violation in decays of the Z boson with the ATLAS detector at the LHC are presented. Decays of the Z boson into an electron or muon and a hadronically decaying τ lepton are considered. The searches are based on a data sample of proton-proton collisions collected by the ATLAS detector in 2015 and 2016, corresponding to an integrated luminosity of 36.1 fb−1 at a center-of-mass energy of ffiffi s p ¼ 13 TeV. No statistically significant excess of events above the expected background is observed, and upper limits on the branching ratios of lepton-flavor-violating decays are set at the 95% confidence level: BðZ → eτÞ < 5.8 × 10−5 and BðZ → μτÞ < 2.4 × 10−5. This is the first limit on BðZ → eτÞ with ATLAS data. The upper limit on BðZ → μτÞ is combined with a previous ATLAS result based on 20.3 fb−1 of proton-proton collision data at a center-of-mass energy of ffiffi s p ¼ 8 TeV and the combined upper limit at 95% confidence level is BðZ → μτÞ < 1.3 × 10−5.en_US
