Book excerpt: A direct search for lepton-flavour-violating H → [mu][tau] decays of the recently discovered Higgs boson with the ATLAS detector at the LHC is presented. The analysis is performed in the H → [mu][tau] had channel, where [tau] had is a hadronically decaying [tau] -lepton. The search is based on the data sample of proton-proton collisions collected by the ATLAS experiment corresponding to an integrated luminosity of 20.3 fb-1 at a centre-of-mass energy of √s = 8 TeV. No statistically significant excess of data over the predicted background is observed. As a result, the observed (expected) 95% confidence-level upper limit on the branching fraction, Br( H → [mu][tau] ), is 1.85% (1.24%).
