Abstract
The production ofD +S mesons inB meson decays, and inq \(\bar q\) continuum events, has been studied with the ARGUS detector at thee + e − storage ring DORIS II. In addition to the measurement of inclusiveD + S production in γ(4S)→B \(\bar B\) decays, all eight two-body decay modesB→D (*)S D (*) have been measured with branching ratios between 1% and 3%. By comparing our inclusive and exclusive results to predictions of heavy quark effective theory, a value of (267±28) MeV × [2.7%/BR(D + s →φπ+)]1/2 is obtained for the weak decay constant fD (*) S , averaged overD + S andD *+ S mesons.
