Abstract

We report the results of a search for T, CP, and CPT violation in B0-B̅ 0 mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B factory. Using a sample of 232×106 BB̅ pairs, we measure the T and CP violation parameter |q/p|-1=(-0.8±2.7(stat)±1.9(syst))×10-3, and the CPT and CP parameters Imz=(-13.9±7.3(stat)±3.2(syst))×10-3 and ΔΓ×Rez=(-7.1±3.9(stat)±2.0(syst))×10-3  ps-1. The statistical correlation between the measurements of Imz and ΔΓ×Rez is 76%.
