The Measurement of D+(s) and D+ meson decays into anti-K*+ anti-K*0

Using the ARGUS detector at thee+e− storage ring DORIS II at DESY, we have observed the decaysD+→K−K0π+π+ andDs+→K−K0π+π+. The branching ratios were determined to be BR(D+→K−K0π+π+)=(1.0±0.5±0.3)% and BR(Ds+→K−K0π+π+)/BR(Ds+→φπ+)=1.2±0.2±0.2. These decays are found to proceed mostly via the

\bar K*^0 K*^ +

decay channel, with BR(D+→

\bar K*^0 K*^ +

)=2.6±0.8±0.7)% and BR(Ds+→

\bar K*^0 K*^ +

)/BR(Ds+→φπ+)=1.5±0.4±0.4.
