Search for **R**-parity violating decays of sneutrinos to $e\mu$, $\mu\tau$, and $e\tau$ pairs in $p\overline{p}$ collisions at $\sqrt{s}$=1.96 TeV

We present a search for supersymmetric neutrino (nu) over tilde production using the Tevatron p (p) over bar collision data collected with the CDF II detector and corresponding to an integrated luminosity of 1 fb(-1). We focus on the scenarios predicted by the R-parity violating (RPV) supersymmetric models in which sneutrinos decay to two charged leptons of different flavor. With the data consistent with the standard model expectations, we set upper limits on sigma(p (p) over bar -> (nu) over tilde) BR((nu) over tilde -> e mu, mu tau, e tau) and use these results to constrain the RPV couplings as a function of the sneutrino mass.
