Abstract

An overview is given on the first observation of a mode that is directly accessible through the spectator process. The mode ̄B⁰→D_s⁺K^- may occur via W exchange or final rescattering, and predictions for its branching fraction vary over a wide range, 3X10^-6-10^-. The search for ̄B⁰→D_s⁺K^- also encompasses B⁰→D_s⁺π^-, a mode expected to be dominated by a (spectator) b→u transition.

N2 - An overview is given on the first observation of a mode that is directly accessible through the spectator process. The mode ̄B0→Ds+K- may occur via W exchange or final rescattering, and predictions for its branching fraction vary over a wide range, 3X10-6-10-. The search for ̄B0→Ds+K- also encompasses B0→Ds+π-, a mode expected to be dominated by a (spectator) b→u transition.
