We have searched for a neutral H dibaryon decaying via H→Λn and H→Σ0n. Our search has yielded two candidate events from which we set an upper limit on the H production cross section. Normalizing to the inclusive Λ production cross section, we find (dσH / dΩ) / (dσΛ / dΩ)<6.3×10-6 at 90% C.L., for an H of mass ≈2.15 GeV/c2.
