抄録

A search for double-Λ hypernuclei ((ΛΛ)/¹²Be) and H-dibaryons using the ¹²C(K^-, K⁺) reaction was performed at the BNL-AGS using a high-intensity 1.8 GeV/c K^- beam. A missing-mass analysis below the end point of the quasi-free Ξ^- production was used to investigate these S = -2 systems. The upper limit obtained for the forward-angle cross section of (ΛΛ)/¹² Be production is 6 to 10 nb/sr. This is the first search for the direct production of double-Λ hypernuclei to reach the sensitivity required to observe the signal predicted by theoretical calculations. For the H-production cross section, we have obtained an upper limit in the range of a few nb/sr to 10 nb/sr for the H mass below 2100 MeV/c². This upper limit is the most sensitive H search result to date for a tightly bound H. (C) 2000 Published by Elsevier Science B.V.
