Abstract
We report on a measurement of the differential cross sections of inclusive $K^{\pm}_{890}$ production in $\Sigma^{-}$, $\pi^{-}$ and neutron beams. A strong leading particle effect was observed for K-890 production by $\Sigma^{-}$. The measured xF-distributions are compared with calculations based on the Lund model (PYTHIA) and the quark-gluon string model.
