Abstract
Direct searches for lepton flavour violation in
decays of the Higgs and Z bosons with the ATLAS detector
at the LHC are presented. 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.
