Abstract | |||||||||||||
| CERN experiment WA89 has studied charmed particles produced by a \Sigma \Gamma beam at 340GeV=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 D \Gamma and D + , D \Gamma s and D + s and c and c are observed. The results are compared with pion beam data and with theoretical calculations.
