Abstract
We present results of a search for a new form of hadronic matter, a six-quark, dibaryon state called the , a state predicted to exist in several theoretical models. Analyzing data collected by experiment E799-II at Fermilab, we searched for the decay and found no candidate events. We place an upper limit on and, in the context of published models, exclude the region of lightly bound mass states just below the mass threshold, , with lifetimes from to .
