Abstract
We report on two null searches, one for the spontaneous appearance of π+ π- pairs, another for a single π0, 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 R0, we exclude the decays R0 #x2192; π+π- γ for the masses of R0 and γ in the theoretically allowed range. In the most interesting R0 mass range, ≤ 3 GeV/c2, we exclude R0 lifetimes from 3 #x00D7; 10-10 sec to as high as 10-3 sec, assuming perturbative QCD production for the R0.
