Search 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 LHC    [PDF]

ATLAS Collaboration

This letter presents the results of a search for a heavy particle decaying into an e mu, e tau, or mu tau final state in pp collisions at sqrt(s) = 7 TeV. The data were recorded with the ATLAS detector at the LHC during 2011 and correspond to an integrated luminosity of 4.5/fb. No significant excess above the Standard Model expectation is observed, and exclusions at 95% confidence level are placed on the cross section time branching ratio for the production of an R-parity-violating supersymmetric tau sneutrino. These results considerably extend constraints from Tevatron experiments.
