MEASUREMENT OF D MESON BRANCHING RATIOS

Charm data from 360 GeV/c π̅ p interactions are used to give results on D-meson branching ratios. The analysis is based on 114 charm events containing 183 observed charm particle decays. We present topological branching ratios and decay multiplicities, as well as the following inclusive branching ratios of D-mesons: B(D± → K∓+ anything) = 0.16+0.08−0.007, if B(D0 → K ± + anything) = 0.44+0.11−0.10, if B(D±→e± +2,4 (rmcharged hadrons) = 0.07+0.08−0.05, B(D0→e± + anything) = 0.17+0.08−0.06

NEUTRAL AND CHARGED D* PRODUCTION IN 360-GeV/c pi- p INTERACTIONS

The first data on the production of D∗(2010) are presented as observed in π̅ -proton interactions at √s = 27 GeV. It is found that D∗(2010) dominates the total charm D-meson production, without a significant non-central component
