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 D0 experiment and correspond to an integrated luminosity of 94±5 pb-1. Assuming that R parity is violated via the single coupling λ211′, the number of candidate events is in agreement with expectation from the standard model. Exclusion contours are given in the (m0,m1/2) and (mχ ˜,mν ˜) planes for λ211′=0.09, 0.08, and 0.07.
