Abstract
We searched for the appearance of pairs with invariant mass in a neutral beam. Such an observation could signify the decay of a long-lived light neutral particle. We find no evidence for this decay. Our null result severely constrains the existence of an hadron, which is the lightest bound state of a gluon and a light gluino , and thereby also the existence of a light gluino. Depending on the photino mass, we exclude the in the mass and lifetime ranges of and , respectively.
