Abstract
CERN experiment WA89 has studied charmed particles produced by a Sigma(-) b eam at 340 GeV/c on nuclear targets. Production of particles which have lig ht quarks in common with the beam is compared to production of those which do not. Considerable production asymmetries between D- and D+, D-s(-) and D -s(+) and A(c) and (A) over bar(c) are observed. The results are compared w ith pion beam data and with theoretical calculations.
