Abstract

We describe a general search for resonances decaying to a neutral

e μ

final state in

p \bar{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 Collider Detector at Fermilab II experiment, we compare standard model predictions with the number of observed events for invariant masses between 50 and

800 GeV / c^{2}

. Finding no significant excess (5 events observed vs

7.7 \pm 0.8

expected for

M_{e μ} > 100 GeV / c^{2}

), we set limits on sneutrino and

Z^{'}

masses as functions of lepton family number violating couplings.
