Phys. Rev. Lett. 76, 3277–3280 (1996)Search for the Weak Decay of an H DibaryonReceived 8 December 1995; published in the issue dated 29 April 1996 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. © 1996 The American Physical Society URL:
