Resumen:
A search is presented for a high mass neutral particle
that decays directly to the emu final state. The data sample was
recorded by the ATLAS detector in sqrt(s) = 7 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 emu 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.
