摘要：

Experiment WA82 studied charm production by a pi- beam of 340 GeV/c at the CERN OMEGA' spectrometer, using a silicon microstrip vertex detector and an impact parameter trigger. Results on the x(F) distributions of D+ and D-mesons are presented and discussed. A clear excess of D- over D+, increasing at high x(F), is observed.
