Probing lepton flavour violation via neutrinoless τ → 3μ decays with the ATLAS detector

This article presents the sensitivity of theATLAS experiment to the lepton-flavour-violating decays of τ → 3μ. A method utilising the production of τ leptons via W → τν decays is used. This method is applied to the sample of 20.3 fb<SUP>-1</SUP> of <i>pp</i> collision data at...
