Measurement of the B0 lifetime and oscillation frequency using decays

The lifetime and oscillation frequency of the B0 meson has been measured using decays recorded on the Z0 peak with the OPAL detector at LEP. The decays were reconstructed using an inclusive technique and the production flavour of the B0 mesons was determined using a combination of tags from the rest of the event. The results were obtained, where in each case the first error is statistical and the second is systematic.
