Search for a heavy narrow resonance decaying to eμ eτ or μτ with the ATLAS detector in √s=7 TeV pp collisions at the LHC

This Letter presents the results of a search for a heavy particle decaying into an e ± μ ∓ , e ± τ ∓ , or μ ± τ ∓ final state in pp collisions at s=7 TeV. The data were recorded with the ATLAS detector at the LHC during 2011 and correspond to an integrated luminosity of 4.6 fb −1 . No significant ex...
