Search for the H dibaryon in (K-,K+) reactions

We have studied ({ital K}{sup {minus}},{ital K}{sup +}) reactions from an emulsion target. The {ital S}={minus}2 {ital H} dibaryon has been searched for by the analysis of the {ital K}{sup +} momentum spectrum together with emulsion data. No evidence of {ital H} production was observed in the mass r...

Zusammenfassung:We have studied ({ital K}{sup {minus}},{ital K}{sup +}) reactions from an emulsion target. The {ital S}={minus}2 {ital H} dibaryon has been searched for by the analysis of the {ital K}{sup +} momentum spectrum together with emulsion data. No evidence of {ital H} production was observed in the mass range of 1.90--2.16 GeV/{ital c}{sup 2}. Upper limits for the production cross section of the {ital H} are (0.2--0.6)% of that for the quasifree {Xi}{sup {minus}} production at the 90% confidence level.
