Measurement ofD0 decays into\(\overline {K^0 } \omega \),\(\overline {K^0 } \eta \) and\(\overline {K^{*0} } \eta \)

Using the ARGUS detector at the electron-positron storage ring DORIS II at DESY, we have measured the branching ratios of theD0 meson decays into\(\overline {K^0 } \omega \),\(\overline {K^0 } \eta \) and\(\overline {K^{*0} } \eta \) relative to theK−π+ mode. Using the known branching ratio Br(D0→Kπ+)=(4.2±0.4±0.4)% we find\(Br(D^0 \to \overline {K^0 } \omega ) = (4.2 \pm 1.6 \pm 0.9)\% ,Br(D^0 \to \overline {K^0 } \eta )< 2.7\% \) (90% CL) and\(Br(D^0 \to \overline {K^{*0} } \eta )< 2.9\% \) (90% CL).
