Abstract
We report on two null searches, one for the spontaneous appearance of pairs, another for a single , consistent with the decay of a long-lived neutral particle into hadrons and an unseen neutral particle. For the lowest level gluon-gluino bound state, known as the , we exclude the decays and for the masses of and in the theoretically allowed range. In the most interesting mass range, , we exclude lifetimes from to as high as , assuming perturbative QCD production for the .
