$\Xi^-$ and $\Omega$ Distributions in Hadron-Nucleus Interactions

Abstract

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