Abstract:
We report on a measurement of the inclusive production cross sections for Z(+/-), Z(1385)(+/-), Z(1660)(+/-) and (&USigma;) over bar ((1) over bar 385) in the CERN hyperon beam experiment WA89, using a Sigma(-)/pi(-) beam of 345 GeV/c momentum and neutrons of 260 GeV/c mean momentum. A strong leading particle effect was observed for all negative Sigma and Sigma*. The results are compared with predictions from phenomenological models.
