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

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