Scientific paper

We report a study of T and CP violation in B^0 \overline B^0 mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B Factory. The asymmetry between l^+ l^+ and l^- l^- allows us to compare the probabilities for \overline B^0 → B^0 and B^0 → \overline B^0 oscillations and thus probe T and CP invariance. Using a sample of 23 million B \overline B pairs, we measure a same-sign dilepton asymmetry of AT and for the modulus of the ratio of complex mixing parameters p and q.
