Search for rareB meson decays intoD + s mesons

Abstract

A search has been performed for rareB meson decays intoD s mesons arising frombu transitions,W exchange modes,B + annihilation processes, and decays where theD + s is not produced via aWc \(\bar s\) 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 ofD + s - correlations an upper limit of BR (BD + s - X) (90% CL) is determined.
