Abstract
We report on a measurement of the inclusive cross sections of $\Lambda$, $\overline{\Lambda}$, K 0S, $\overline{\Xi}^{+}$ and $\Omega^{-}$ production by $\Sigma^{-}$and $\pi^{-}$of 345 GeV/C momentum and by neutrons of 260 GeV/c mean momentum in copper and carbon. The differential cross sections as function of p2t show a distinct non-gaussian behavior above 1.2 (GeV/c)2. A comparison of the xF-dependence of $\Lambda$, $\overline{\Lambda}$ and K 0 production with calculations using PYTHIA and the QGSM model is discussed.
