The experiment:

The Σ- hyperons were produced by stopping K--mesons in the 81 cm Saclay Hydrogen Bubble Chamber at the CERN PS. The film was scanned for Σ- p interactions with a visible Λ decay. Only events where the Σ- hyperon came to rest were considered.

The data:

For the inelastic Σ- p reaction the capture ratio at rest is
r<sub>c</sub> = 0.474 ± 0.016


The uncertainty includes statistical and systematical uncertainties. 16 June 2024
