Search for the production of single sleptons through R-parity violation in pp̅ collisions at √s=1.8 TeV

Abstract

We report the first search for supersymmetric particles via s-channel production and decay of smuons or muon sneutrinos at hadronic colliders. The data for the two-muon and two-jets final states were collected by the DØ experiment and correspond to an integrated luminosity of 94±5 pb^-1. Assuming that R parity is violated via the single coupling λ'₂₁₁, the number of candidate events is in agreement with expectation from the standard model. Exclusion contours are given in the (m₀,m_½) and (m_x˜,m_v˜) planes for λ'₂₁₁=0.09, 0.08, and 0.07.
