Abstract: (Elsevier)
The time dependent mixing of B d 0 – B d 0 mesons has been observed by using the correlations between the charge of D ∗ mesons and the weighted mean charge of particles in each hemisphere. From a reconstructed D ∗± sample corresponding to about 1.7 million hadronic Z 0 decays, the mass difference between the two B d 0 mass eigenstates has been measured to be Δm = 0.50±0.12 ( stat. ) ± 0.06 ( syst. ) h ̵ / ps or, converting into eV/ c 2 : Δm = [3.29 ± 0.79 (stat) ± 0.39 (syst.)] 10 −4 eV/c 2 .- electron positron: colliding beams
