INCLUSIVE NEUTRAL-D PRODUCTION IN 205-GEV/C PI-BE INTERACTIONS

Hadronic charm production was investigated with a two-arm magnetic spectrometer. The experiment was triggered on muons from the semileptonic decay of charm particles in one arm while reconstructing the mass of the associatively produced partners in the other arm. An excess of 153 +/- 46 combinations...

Beschreibung
Zusammenfassung:	Hadronic charm production was investigated with a two-arm magnetic spectrometer. The experiment was triggered on muons from the semileptonic decay of charm particles in one arm while reconstructing the mass of the associatively produced partners in the other arm. An excess of 153 +/- 46 combinations above background for the neutral D --> K-pi mode was observed. This corresponds to a model-dependent DDBAR production cross section of 41 +/- 12(-11)+15-mu-b per nucleon, where the first uncertainty is statistical and the second is systematic.
