Abstract

We report a search for R-parity-violating production and decay of sneutrino particles in the e μ final state with 1.04 ± 0.06 fb^-1 of data collected with the D₀ detector at the Fermilab Tevatron Collider in 2002–2006. Good agreement between the data and the standard model prediction is observed. With no evidence for new physics, we set limits on the R-parity-violating couplings λ′ ₃₁₁ and λ ₃₁₂ as a function of the sneutrino mass.
