New results onD 0 decays

Using the ARGUS detector at thee + e − storage ring DORIS II, we have studied nine decay modes of theD 0 meson. In addition to a higher-precision determination of the branching ratios for these modes, several new channels, the decays $$D^0 \to \bar K^0 \eta '$$ , $$D^0 \to \bar K^{*0} \omega $$ and $$D^0 \to \bar K\pi ^ + \omega $$ , have been observed for the first time.
