Measurement of D 0 decays intooverline {K^0 } ω ,overline {K^0 } η andoverline {K^{*0} } η
Abstract
Using the ARGUS detector at the electron-positron storage ring DORIS II at DESY, we have measured the branching ratios of the D 0 meson decays intooverline {K^0 } ω ,overline {K^0 } η andoverline {K^{*0} } η relative to the K -π+ mode. Using the known branching ratio Br( D 0→ Kπ+)=(4.2±0.4±0.4)% we findBr(D^0 to overline {K^0 } ω ) = (4.2 ± 1.6 ± 0.9)% ,Br(D^0 to overline {K^0 } η )< 2.7% (90% CL) andBr(D^0 to overline {K^{*0} } η )< 2.9% (90% CL).
