Abstract

The production of J/ψ in B meson decays has been measured on the Γ(4 S) resonance using the Crystal Ball detector at the e⁺e^- storage ring DORIS II. The J/ψ is identified by its e⁺e^- decay mode. We obtain a branching ratio of BR(B→J/ψX)=(1.12±0.33±0.25)% in good agreement with theoretical predictions based on color suppression. The J/ψ momentum distribution is observed to be peaked at high values. This implies a substantial contribution from direct B meson decays to the J/ψ. In addition upper limits on J/ψ production in Γ(1 S) and Γ(2 S) decays and in continuum processes are determined.
