摘要：

We have studied (K-,K+) reactions from an emulsion target. The S=-2 H dibaryon has been searched for by the analysis of the K+ momentum spectrum together with emulsion data. No evidence of H production was observed in the mass range of 1.902.16 GeV/c2. Upper limits for the production cross section of the H are (0.20.6)% of that for the quasifree z- production at the 90% confidence level. © 1990 The American Physical Society.
