Production of D, D^* and D_s mesons in 200 GeV/c π^-K^- and p-Si interactions

The NA 32 experiment at the CERN SPS has collected 38 million hadronic interactions with incident 200 GeV/c π^-, K^- and p beam. Using a segmented silicon active target and a telescope of high resolution silicon microstrip counters we have selected fully reconstructed D⁰→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 for D^o, D⁺D^*+ and D_s⁺ meson production and the dependence of the cross-section on longitudinal and transverse momentum of the D are presented.
