A determination of branching ratios for D meson decays into all charged particle final states is reported. The values obtained: (D ± → K ∓π ±π ±/all D ±) = (14 ± 6)% and ( D 0/D 0 → K ±π ∓π +π −/all D 0/D 0) = (10 ± 4)%, are higher than those currently accepted. This result, if confirmed, implies a corresponding reduction in the accepted values for some total cross section measurements. Revised inclusive cross sections for D meson production in the forward hemisphere in π −p and pp interactions at 360 GeV/ c, are presented.
