Abstract
We report the results of a search for T and CP violation in B-0-(B) over bar (0) mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B Factory. The asymmetry between .(+).(+) and .(-).(-) events allows us to compare the probabilities for (B) over bar (0)-->B (0) and B-0-->(B) over bar (0) oscillations and thus probe T and CP invariance. Using a sample of 23x10(6) B (B) over bar pairs, we measure a same-sign dilepton asymmetry of A(T/CP)=[0.5+/-1.2(stat) +/-1.4(syst)]% . For the modulus of the ratio of complex mixing parameters p and q , we obtain parallel toq/pparallel to=0.998+/-0.006(stat) +/-0.007(syst) .
