Production ofD, D * andD s mesons in 200 GeV/c ?? K ? andp-Si interactions

The NA 32 experiment at the CERN SPS has collected 38 million hadronic interactions with incident 200 GeV/c π−,K− andp beam. Using a segmented silicon active target and a telescope of high resolution silicon microstrip counters we have selected fully reconstructedD0→K−π+,D0→K−π+π+π−,D+→K−π+π+,D s + →K−K+π+π+ and charge conjugate decays. The integrated cross-sections forDo,D+D*+ andD s + meson production and the dependence of the cross-section on longitudinal and transverse momentum of theD are presented.
