Search for lepton-flavour-violating H → μτ decays of the Higgs boson with the ATLAS detector

A direct search for lepton-flavour-violating H → μτ decays of the recently discovered Higgs boson with the ATLAS detector at the LHC is presented. The analysis is performed in the H → μτ<sub>had</sub> channel, where τ<sub>had</sub> is a hadronically decaying τ-lepton. The sea...
