Abstract
Neutral B meson oscillations in the and 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 system was measured to be: The following limit on the width difference of these states was also obtained: As no evidence for oscillations was found, a limit on the mass difference of the two physical states was given: The corresponding sensitivity of this analysis is equal to 6.6 ps-1.
