Abstract This article presents the sensitivity of the ATLAS experiment to the lepton-flavour-violating decays of τ3μ. A method utilising the production of τ leptons via Wτν decays is used. This method is applied to the sample of 20.3fb1 of pp collision data at a centre-of-mass energy of 8TeV collected by the ATLAS experiment at the LHC in 2012. No event is observed passing the selection criteria, and the observed (expected) upper limit on the τ lepton branching fraction into three muons, Br(τ3μ), is 3.76×107 (3.94×107) at 90% confidence level.
