WA46_1984_I206647
The WA46 experiment measured the asymmetry parameter in the decays $\Omega^-\to\Lambda^0K^-$, $\Omega^-\to\Xi^0\pi^-$ and $\Omega^-\to\Xi^-\pi^0$. In practice this is a fit to a normalised distribution $\frac12(1+\alpha\cos\theta)$. The paper only gives the number for the $\alpha$ parameter and not the distribution, so the distribution is calculated. The $\alpha$ parameter is then extracted using a $\chi^2$ fit. This analysis is useful for testing spin correlations in hadron decays.
