【 摘 要 】

The asymmetry between same sign inclusive dilepton samples ++and --from semileptonic B decays in Υ (4S) → BoBoevents allows to compare B mixing probabilities P(Bo→ Bo) and P(Bo→ Bo) therefore to test the T and CP invariance. We present the measurement of CP asymmetry in inclusive dilepton samples with the full BABAR data set near the Υ(4S) resonance, corresponding to 471 million of pairs.
