Abstract

We describe measurements of CP and CPT violation parameters in B⁰B⁰bar oscillations, performed at BaBar by using BBbar events collected at the Y(4S) mass peak. These are obtained from two different B-reconstruction methods, namely: searching for two inclusive semileptonic B⁰ decays in an event or partially reconstructing one of the B⁰ mesons in the D* l nu_l channel. The results are in agreement with one another and with the most recent theoretical calculations in the Standard Model scenario.
