We have searched for the production and decay of light supersymmetric baryons produced in 800GeV/c proton copper interactions in a charged hyperon beam experiment. We observe no evidence for the decays R+(uud\stackrel\ifmmode \else \~\fig)\ensuremath→S0(uds\stackrel\ifmmode \else \~\fig)\ensuremathπ+ and X^\ensuremath-(ssd\stackrel\ifmmode \else \~\fig)\ensuremath→S0(uds\stackrel\ifmmode \else \~\fig)\ensuremathπ^\ensuremath- in the parent mass and lifetime ranges of 1700--2500MeV/c2 and 50--500 ps. Production upper limits for R+ at xF\phantom\rule0ex0ex=\phantom\rule0ex0ex0.47, Pt\phantom\rule0ex0ex=\phantom\rule0ex0ex1.4GeV/c2 and X^\ensuremath- at xF\phantom\rule0ex0ex=\phantom\rule0ex0ex0.48, Pt\phantom\rule0ex0ex=\phantom\rule0ex0ex0.65GeV/c2 of less than 10^\ensuremath-3 of all charged secondary particles produced are obtained for all but the highest masses and shortest lifetimes predicted.
