We report a study of T and CP violation in B[sup 0][bar B][sup 0] mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B Factory. The asymmetry between[ell][sup+][ell][sup+] and[ell][sup -][ell][sup -] allows us to compare the probabilities for[bar B][sup 0][yields] B[sup 0] and B[sup 0][yields][bar B][sup 0] oscillations and thus probe T and CP invariance. A sample of 20,381 same-sign dilepton events is selected in the 1999--2000 data sample, corresponding to an integrated luminosity of 20.7 fb[sup -1] on the[Upsilon](4S) resonance. We measure a same-sign dilepton asymmetry of A[sub T]= (0.5[+-] 1.2[+-] 1.4)%; for the parameter[epsilon][sub B] representing T and CP violations in mixing, we obtain a preliminary result of Re([epsilon][sub B])/1+[epsilon][sub B][sup 2]= (1.2[+-] 2.9[+-] 3.6) x 10[sup -3].

The authors report the results of a search for T and CP violation in B[sup 0]-[bar B][sup 0] mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B Factory. The asymmetry between[ell][sup+][ell][sup+] and[ell][sup -][ell][sup -] events allows the authors to compare the probabilities for[bar B][sup 0][yields] B[sup 0] and B[sup 0][yields][bar B][sup 0] oscillations and thus probe T and CP invariance. Using a sample of 23 million B[bar B] pairs, they measure a same-sign dilepton asymmetry of A[sub T/CP]= (0.5[+-] 1.2(stat)[+-] 1.4(syst))%. For the modulus of the ratio of complex mixing parameters p and q, they obtainq/p= 0.998[+-] 0.006(stat)[+-] 0.007(syst).

We report a study of T and CP violation in B°{bar B}° mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B Factory. The asymmetry between ll and l−l− allows us to compare the probabilities for {bar B}° 2!B° and B° 2!{bar B}° oscillations and thus probe T and CP invariance. A sample of 20,381 same-sign dilepton events is selected in the 1999--2000 data sample, corresponding to an integrated luminosity of 20.7 fb−1 on the [Upsilon](4S) resonance. We measure a same-sign dilepton asymmetry of A{sub T} = (0.5 ± 1.2 ± 1.4)%; for the parameter [epsilon]{sub B} representing T and CP violations in mixing, we obtain a preliminary result of Re([epsilon]{sub B})/1 +
