${\Xi }^{-}$ 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.
