Abstract

We have studied (K-, K+) reactions at P-k- = 1.66 GeV/c by using a newly developed active target made of plastic scintillating fibers. The H dibaryon (S = -2, I(J(pi)) = 0(0(+))) has been searched for through the direct process, K- + C--> K+ + H + X, by the analysis of the K+ momentum spectrum with the help of visual data of the scintillating fiber target. No evidence for the H production was observed, Upper limits for the differential cross section for the H production in the forwarddirection of the K+ is 0.04-0.6 mu b/sr at the 90% confidence level for the H mass range from 1850 to 2215 MeV/c(2).
