Abstract

Using the ARGUS detector at the e⁺e^- storage ring DORIS II at DESY, we have made two measurements of the mixing parameter χ_d using kaons as flavour tags. Using D*⁺ K^± correlations we found χ_d = 0.20 ± 0.13 ± 0.12 and from the study of (D*⁺ℓ^-) K^± correlations we obtained χ_d = 0.19 ± 0.07 ± 0.09. The branching ratio for B̄ → D*⁺ X has been updated: Br(B̄ → D*⁺ X) = (19.6 ± 1.9)%. We have also determined the average multiplicity of charged kaons in B⁰ decays to be 0.78 ± 0.08.
