Search for {ital H} dibaryon-nucleus bound states in relativistic Au+Pt collisions
Recent estimates suggest that the production of strange exotic objects, such as the hypothetical {ital H} dibaryon ({ital H}), is surprisingly large in Au collisions at AGS energies. Two possible bound states of the {ital H}, namely {ital H}-{sup 3}He and {ital H}-{ital d}, would be well separated in mass from known nuclear isotopes and therefore could be uniquely identified by experiment. We report the null result of a first search for these objects in Au+Pt collisions at the AGS, and limit their production cross sections for stable systems to {similar_to}10{sup {minus}5} mb/(GeV){sup 2}, near {ital y}=0.6 and {ital p}{sub {ital t}}/{ital Z}=0.18 GeV/{ital c}.
