Abstract

We report the results of a search for T, CP, and CPT violation in B0−¯¯¯B0 mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B factory. Using a sample of 232×106 B¯¯¯B 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%.
