A study of \(\Sigma^{\pm}\), \(\Sigma^{*\pm}\) and \(\overline{\Sigma}^-_{1385}\) production in the hyperon beam experiment WA89 at CERN
2001
We report on a measurement of the inclusive production cross sections for \(\Sigma^{\pm}\), \(\Sigma^{\pm}_{1385}\), \(\Sigma^{\pm}_{1660}\) and \(\overline{\Sigma}^-_{1385}\) 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.
