We have searched for the production and decay of light supersymmetric baryons produced in 800 GeV/c proton copper interactions in a charged hyperon beam experiment. We observe no evidence for the decays R+(uudg̃)→S0(udsg̃)π+ and X-(ssdg̃)→S0(udsg̃)π- in the parent mass and lifetime ranges of 1700–2500 MeV/c2 and 50–500 ps. Production upper limits for R+ at xF  =  0.47, Pt  =  1.4 GeV/c2 and X- at xF  =  0.48, Pt  =  0.65 GeV/c2 of less than 10-3 of all charged secondary particles produced are obtained for all but the highest masses and shortest lifetimes predicted.
