title = "Search for light gluinos via the spontaneous appearance of π+ π− Pairs with an 800 GeV/c proton beam at fermilab",
abstract = "We searched for the appearance of π+ π− pairs with invariant mass ≥ 648 MeV/c2 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 R0 hadron, which is the lightest bound state of a gluon and a light gluino (g∼g), and thereby also the existence of a light gluino. Depending on the photino mass, we exclude the R0 in the mass and lifetime ranges of 1.2 − 4.6 GeV/c2 and 2 × 10−7 × 10−4s, respectively.",
