Abstract
- Charm data from 360 GeV/c π−p and 400 GeV/cpp interactions are used to give results onD-meson branching ratios. The analysis is based on 438 charm events containing 608 spatially resolved charm particle decays. We present topological branching ratios, as well as the following inclusive branching ratios ofD-mesons into kaons: $$\begin{gathered} B(D^ \pm \to K^ \mp + anything) = 0.17 \pm 0.07, \hfill \\ B(D^ \pm \to K^ \pm + anything) = 0.08_{ - 0.05}^{ + 0.06} , \hfill \\ B(D^0 \to K^ \pm + anything) = 0.42 \pm 0.08, \hfill \\ B(D^0 \to K^ + + anything) = 0.03_{ - 0.02}^{ + 0.05} , \hfill \\ \end{gathered} $$ and the following semi-electronic branching ratios ofD-mesons: $$\begin{gathered} B(D^ \pm \to e^ \pm + anything) = 0.20_{ - 0.07}^{ + 0.09} , \hfill \\ B(D^0 \to e^ \pm + anything) = 0.15 \pm 0.05. \hfill \\ \end{gathered} $$
