Abstract

We report the first observation of the decay Ds+K 0K+ and a new measurement of the decay Ds+K (892)0K+. The data were collected at s=4.14 GeV with the Mark III detector at the SLAC e+e- storage ring at SPEAR. We obtain the relative branching fractions B(D+sK0K+/ B(Ds++)=0.920.320.20 and B(Ds+K*0K+)/ B(Ds++)=0.840.300.22, using our new determination of B(Ds++). A search for the Cabibbo-suppressed decay D+sK0+ yields a limit B(Ds+K0+)/B(Ds++)<0.21 at the 90% confidence level.
