The WA46 experiment measured the asymmetry parameter in the decays Ω−→Λ0K−, Ω−→Ξ0π− and Ω−→Ξ−π0. In practice this is a fit to a normalised distribution 12(1+αcosθ). The paper only gives the number for the α parameter and not the distribution, so the distribution is calculated. The α parameter is then extracted using a χ2 fit. This analysis is useful for testing spin correlations in hadron decays.
