Abstract
We have searched for the production and decay of light supersymmetric baryons produced in proton copper interactions in a charged hyperon beam experiment. We observe no evidence for the decays and in the parent mass and lifetime ranges of and 50–500 ps. Production upper limits for at , and at , of less than of all charged secondary particles produced are obtained for all but the highest masses and shortest lifetimes predicted.
