摘要：

An emulsion-counter hybrid experiment (KEK E176) was carried out to search for double strangeness systems such as double-Lambda hypernuclei and H-dibaryons. More than 10% of Xi(-) hyperons produced in the (K-, K+) reaction were brought to rest in the nuclear emulsion. We have obtained 98 candidate events of nuclear capture at rest of Xi(-) hyperons which are described in this report. Among those, four events were identified as sequential weak decay of double-Lambda hypernuclei. The binding energies of Xi(-)-(C-12, N-14 and O-16) states have been estimated for two events which emit twin single-Lambda hypernuclei back to back from the capture point. The Sigma(-)p decay vertex of an H-dibaryon was searched for near the capture point and no evidence was observed. Upper limits for the branching ratio of H emission are 5-10% for a lifetime less than 0.1 ns at the 90% confidence level. The trapping probabilities of single and double strangeness to a nuclear fragment following Xi(-) capture at rest have been studied. (C) 2009 Elsevier B.V. All rights reserved.
