Abstract

Results are presented on a new measurement of $α P$ for the decay of $Σ^{+}$ hyperons produced in the reaction $K^{-} p \to Σ^{+} π^{-}$ at beam momenta around 460 MeV/c, where $α$ is the decay asymmetry parameter and $P$ is the hyperon polarization. The present analysis is based on 20479 events. The ratio of the usual $Σ^{+}$ decay parameters, $α_{+}$ and $α_{0}$ , is found to be -0.104 ± 0.028; this should be compared with the present world average of -0.067 ± 0.016.
