Abstract (english)

In this analysis we use the Run1-5 BaBar dataset to study the CP violation in BBbar mixing. B -> D* l nu decays are selected by using partial reconstruction of the D*, while the flavor of the un-reconstructed B is tagged from the charge of a kaon identified among its decay products.
Detector related charge asymmetries are measured on data using the kaons coming from the partially reconstructed D*.
A study on the feasibility of the measurement of Doubly Cabibbo Suppressed Decays effective parameters on the tag side is also performed.
