Abstract

Using the ARGUS detector at the e⁺e^- storage ring DORIS II at DESY, we have studied the decay B⁰ → D^*+ ℓ^- v by exploiting a partial D^*+ reconstruction technique. The branching ratio for this mode was thereby determined to be (4.5 ± 0.3 ± 0.4)%. Using the corresponding sample of tagged B⁰ mesons, we measured the B⁰B⁰ mixing parameter to be r_d = 0.194 ± 0.062 ± 0.054, a result only weakly dependent upon the ratio of semileptonic widths for and production rates of B⁰ and B⁺ mesons. We have also determined the branching ratio Br (B⁰ → X ℓ^-v to be (9.3 ± 1.1 ± 1.5)%. By comparing the results for full and partial D^*+ reconstuction we found the absolute branching ratios for D⁰ → K^-π⁺ and D⁰ → K^- π⁺π⁺π^- to be (4.5 ± 0.6 ± 0.4)% and (7.9 ± 1.5 ± 0.9)%, respectively.
