Search For T, CP, and CPT Violation in B0−¯¯¯B0 Mixing with Inclusive Dilepton Events

Abstract

We report the results of a search for T , C P , and C P T violation in B 0 − ¯¯¯ B 0 mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B factory. Using a sample of 232 × 10 6 B ¯¯¯ B pairs, we measure the T and C P violation parameter | q / p | − 1 = ( − 0.8 ± 2.7 ( stat ) ± 1.9 ( syst ) ) × 10 − 3 , and the C P T and C P parameters Im z = ( − 13.9 ± 7.3 ( stat ) ± 3.2 ( syst ) ) × 10 − 3 and Δ Γ × Re z = ( − 7.1 ± 3.9 ( stat ) ± 2.0 ( syst ) ) × 10 − 3 ps − 1 . The statistical correlation between the measurements of Im z and Δ Γ × Re z is 76%.
