Abstract
A search is presented for a high mass neutral particle that decays directly to the e
±
μ
∓ final state. The data sample was recorded by the ATLAS detector in
$\sqrt{s}=7\mbox{~TeV}$
pp collisions at the LHC from March to June 2011 and corresponds to an integrated luminosity of 1.07 fb−1. The data are found to be consistent with the Standard Model background. The high e
±
μ
∓ mass region is used to set 95% confidence level upper limits on the production of two possible new physics processes: tau sneutrinos in an R-parity violating supersymmetric model and Z′-like vector bosons in a lepton flavor violating model.
