Abstract.

CERN experiment WA89 has studied charmed particles produced by a \(\Sigma^-\) beam at 340 GeV/c on nuclear targets. Production of particles which have light quarks in common with the beam is compared to production of those which do not. Considerable production asymmetries between \(\mathrm{D}^-\) and \(\mathrm{D}^+\), \(\mathrm{D}_\mathrm{s}^-\) and \(\mathrm{D}_\mathrm{s}^+\) and \(\Lambda_\mathrm c\) and \(\bar{\Lambda_\mathrm c}\) are observed. The results are compared with pion beam data and with theoretical calculations.
