| Résumé : | Neutral B meson oscillations in the Bs0 - Bs0 and Bd0 - Bd0 systems were studied using a sample of about 4.0 million hadronic Z decays recorded by the DELPHI detector between 1992 and 2000. Events with a high transverse momentum lepton were removed and a sample of 770 k events with an inclusively reconstructed vertex was selected. The mass difference between the two physical states in the Bd0 - Bs0 system was measured to be: Δmd = (0.531 = 0.025(stat.) ± 0.007(syst.))ps-1. The following limit on the width difference of these states was also obtained: |
