Search for R-parity Violating Decays of the Sneutrino into $e\mu$, $\mu\tau$ and $e\tau$ Pairs in $p\bar{p}$ Collisions at $\sqrt{s} = 1.96$ TeV) Public Page

We present a search for a heavy sneutrino decaying into two leptons of different flavors, predicted in R-parity violating supersymmetric models. The search is based on 1~${\rm fb^{-1}}$ of data collected in $p \bar{p}$ collisions by the CDF II Detector at the Fermilab Tevatron. Our results are consistent with the Standard Model expectations and we present 95 \% C.L. upper limits on $\sigma \times \rm BR$ ($p \bar{p} \rightarrow \widetilde{\nu}_{\tau}\rightarrow e\mu,e\tau,\mu\tau$
