Abstract
Analysing high transverse momentum π− nucleus interactions at 40 GeV/c, a search has been made for the hypothetical dibaryon H0 with strangeness −2, spin‐parity 0+ and mass below the two lambda mass. The data came from an experiment performed with a streamer chamber which is well suited to find the H0 through its unique signature of the weak p decay. No H0 event has been found. The 90% confidence upper limit for the observed frequency of production of the H° dibaryon per inelastic π−A collision amounts to 1.5 ·10−4. Cross section upper limits are estimated for C, Cu and Pb targets, also with 90% confidence level.
