- Abstract
- The time dependent mixing of View the MathML source 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 View the MathML source or, converting into eV/c2: Δm = [3.29 ± 0.79 (stat) ± 0.39 (syst.)] 10−4 eV/c2.
