Abstract

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.
