Abstract.

We report on a measurement of the inclusive cross sections of \(\Lambda\), \(\overline\Lambda\), K0S, \(\overline{\Xi}^{+}\)\(\Omega^{-}\) 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 K0 production with calculations using PYTHIA and the QGSM model is discussed.
