Abstract We have measured the differential and total cross sections ofD meson production in 200 GeV π−-beryllium interactions, using a sample of 48 fully reconstructed and nearly background-freeD mesons in the decay channelsK ∓π±,K ∓π±π± andK ∓π∓π±π±. A single electron trigger has been used to select events containing a pair of charmed particles. A vertex telescope of 6 silison microstrip detectors allowed the reconstruction of tracks of charged secondaries and the reconstruction of primary and decay vertices with high precision. The ratio of branching fractions for $$\mathop {D^0 }\limits^{( - )} \to K^ \mp \pi ^ \pm $$ to $$\mathop {D^0 }\limits^{( - )} \to K^ \mp \pi ^ \mp \pi ^ \pm \pi ^ \pm $$ , and an upper limit for $$D^0 - \bar D^0 $$ mixing are presented.
