Review of B oscillation results and inclusive B-reconstruction at LEP

A review of LEP results on B oscillations is presented. Many measurements of the Bd0 oscillation frequency have been performed, yielding a world average of Δmd=0.463±0.018 ps−1. The first time-dependent tests for CP(T) violation in the Bd0 system have now been performed, providing no evidence for CP(T) violation while being consistent with Standard Model expectations. Lower limits on Δms are presented, and the combined LEP results imply Δms>10.2 ps−1 at the 95% confidence level. In addition, techniques for inclusive reconstruction of b-decays are discussed using examples from the ALEPH experiment. Inclusively reconstructed b-decays allow for high statistics analyses of b-lifetimes and oscillations.
