$Ξ^-$ and $Ω$ Distributions in Hadron-Nucleus Interactions

Strange baryons have long been known to exhibit a leading particle effect. A recent comparison of $Ξ^-$ production in $π^-$, $n$, and $Σ^-$ interactions with nuclei show this effect clearly. These data are supplemented by earlier measurements of $Ξ^-$ and $Ω$ production by a $Ξ^-$ beam. We calculate the $Ξ^-$ and $Ω$ $x_F$ distributions and nuclear dependence in $hA$ interactions using the intrinsic model.
