Abstract

Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, we have made two measurements of the mixing parameter χd using kaons as flavour tags. Using D*+ K± correlations we found χd = 0.20 ± 0.13 ± 0.12 and from the study of (D*+-) K± correlations we obtained χd = 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.
