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.
