A Search for Light Super Symmetric Baryons
Abstract
We have searched for the production and decay of light super-symmetric baryons produced in 800 GeV/c proton copper interactions in a charged hyperon beam experiment. We observe no evidence for the decays R+(uud ~) -> S(uds ~) pi+ and X-(ssd ~) -> S(uds ~) pi- in the predicted 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.
