We report on a measurement of the inclusive production cross sections for Σ±, Σ±1385, Σ±1660 and Σ¯−1385 in the CERN hyperon beam experiment WA89, using a Σ−/π− beam of 345 GeV/c momentum and neutrons of 260 GeV/c mean momentum. A strong leading particle effect was observed for all negative Σ and Σ∗. The results are compared with predictions from phenomenological models. (Springer)
