# Search for high-mass resonances decaying to e mu in $p\bar{p}$ collisions at $\sqrt{s} =$ 1.96-TeV

We describe a general search for resonances decaying to a neutral e mu final state in p anti-p collisions at a center-of-mass energy of 1.96 TeV. Using a data sample representing 344 pb-1 of integrated luminosity recorded by the CDF II experiment, we compare Standard Model predictions with the number of observed events for invariant masses between 50 and 800 GeV/c2. Finding no significant excess (5 events observed vs. 7.7 +/- 0.8 expected for M_e mu > 100 GeV/c2), we set limits on sneutrino and Z' masses as functions of lepton family number violating couplings.
