Résumé
A search has been performed for rare B meson decays into Ds- mesons arising from b→u transitions, W exchange modes, B+ annihilation processes, and decays where the Ds+ is not produced via a W→c {Mathematical expression} quark pair coupling, using the ARGUS detector operating on the Ψ(4 S) resonance at the e+e- storage ring DORIS II. Upper limits for individual decay modes are obtained. In addition, from a study of Ds+ℓ- correlations an upper limit of BR (B→Ds+ℓ-X) (90% CL) is determined.
