Abstract

Analyzing $Σ^{-}$ hyperons produced by $K^{-}$ stopping in the 30-in. BNL hydrogen bubble chamber, we have obtained (a) an upper limit for the ratio $\frac{Γ (Σ^{+} \to e^{+} n ν)}{Γ (Σ^{-} \to e^{-} n ν)}$ of 0.018 with 90% confidence and (b) a value for the branching ratio, $\frac{Γ (Σ^{-} \to e^{-} n ν)}{[total Γ (Σ^{-})]}$ , equal to (1.05 ± 0.07) × $10^{- 13}$ , in good agreement with existing data.
