MEASUREMENT OF TIME-DEPENDENT B-D(0) (B)OVER-BAR-D(0) MIXING

Abstract:
The time dependent mixing of Bd0-B̄d0 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 Z0 decays, the mass difference between the two Bd0 mass eigenstates has been measured to be Δm = 0.50±0.12 (stat.) ± 0.06 (syst.) (Latin small letter h with stroke sign)/ps or, converting into eV/c2: Δm = [3.29±0.79 (stat.) ± 0.39 (syst.)] 10-4 eV/c2.
