abstract
We report on a measurement of the inclusive cross sections of Λ, Λ̄, Ks0, Ξ̄%2b and Ω- production by σ- and π- 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 pt2 show a distinct non-gaussian behavior above 1.2 (GeV/c)2. A comparison of the xF-dependence of Λ, Λ̄ and K0 production with calculations using PYTHIA and the QGSM model is discussed.
