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→eτH→eτ , H→μτH→μτ , and Z→μτZ→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−1fb−1 at a centre-of-mass energy of s√=8s=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%(H→eτ)<1.04% , Br (H→μτ)<1.43%(H→μτ)<1.43% , and Br (Z→μτ)<1.69×10−5(Z→μτ)<1.69×10−5 .
