Search for rare B meson decays into D(s)+ mesons

A search has been performed for rareB meson decays intoDs− mesons arising fromb→u transitions,W exchange modes,B+ annihilation processes, and decays where theDs+ is not produced via aW→c

\bar s

quark pair coupling, using the ARGUS detector operating on the Ψ(4S) resonance at thee+e− storage ring DORIS II. Upper limits for individual decay modes are obtained. In addition, from a study ofDs+ℓ- correlations an upper limit of BR (B→Ds+ℓ-X) (90% CL) is determined.
