Résumé : | A sample of some 7500 K- meson captures at rest on hydrogen in emulsion giving rise to charged Σπ pairs has been used to determine r, the decay branching ratio of the Σ+ hyperon, λ, the ratio of Σ-to Σ+ hyperon production, τΣ-, the lifetime of the Σ- hyperon, and C, the mean orbital capture time of Σ- hyperons in emulsion. The results obtained are r= σ+→n+π+ all σ+ decay modes = 0.484 ± 0.015, γ = σ-π+ σ+π- = 2.34 ± 0.08, γσ- = 1.41+0.09-0.08× 10-12sec,andC 10-12sec. © 1969. |
