Abstract

We have searched for a neutral

H

dibaryon decaying via

H \to Λ n

and

H \to Σ^{0} n

. 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

\frac{(\frac{d σ_{H}}{d Ω})}{(\frac{d σ_{Λ}}{d Ω})} < 6.3 \times 10^{- 6}

at 90% C.L., for an

H

of mass ≈2.15 GeV/

c^{2}

.
