Abstract:

The results of a search for T and CP violation in B0-B̄0 mixing were presented. A same-sign dilepton asymmetry was obtained which was used to to extract the modulus of the ratio of complex mixing parameters. The background dilution correction was measured using data from full dilepton sample. The uncertainity on the ratio resulted in a ±3% multiplicative error.

Abstract:

A new technique involving the time-difference distribution of a tagged sample of fully reconstructed neutral B decays was used to determine the B0-B̄0 mixing frequency Δmd. The obtained result is consistent with the current world average and a recent BABAR measurement with a dilepton sample.

Abstract:

An overview is given on the measurement of the time dependence of B0-B̄0 mixing using data collected with the BABAR detector at the PEP-II asymmetric energy e+e- collider operated at or near the Υ(4S) resonance. The result is the single most precise measurements to date and is consistent with a recent BABAR measurement with a fully reconstructed B0 sample, as well as the world average of previous measurements.
