Phys. Rev. Lett. 65, 1729–1732 (1990)Search for the H dibaryon in (K-,K+) reactionsReceived 9 August 1990; published in the issue dated 1 October 1990 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 1.90–2.16 GeV/c2. Upper limits for the production cross section of the H are (0.2–0.6)% of that for the quasifree Ξ- production at the 90% confidence level. © 1990 The American Physical Society URL:
