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 −1 of pp collision data at a centre-of-mass energy of 8 TeV collect...
