The data were recorded with the ATLAS detector at the LHC during 2011 and correspond to an integrated luminosity of 4.6/fb. No significant excess above the Standard Model expectation is observed, and exclusions at 95% confidence level are placed on the cross section times branching ratio for the production of an R-parity-violating supersymmetric tau sneutrino. These results considerably extend constraints from Tevatron experiments.engSearch for a heavy narrow resonance decaying to $e \mu$, $e \tau$, or $\mu \tau$ with the ATLAS detector in $\sqrt{s}=7$ TeV $pp$ collisions at the LHCjournal article2019-02-03
