Abstract

We present results of a search for a new form of hadronic matter a six-quark dibaryon state called the H⁰ a state predicted to exist in several theoretical models. Analyzing data collected by experiment E799-II at Fermilab we searched for the decay H⁰→∧pπ^- and found no candidate events. We place an upper limit on [B(H⁰→∧pπ^-)dσ_H/dΩ]/(dσΞ/dΩ) and in the context of published models exclude the region of lightly bound mass states just below the ∧∧ mass threshold 2.194 < MH < 2.231GeV/c² with lifetimes from ˜5 × 10^-10sec to ˜1 × 10^-3sec.
