Abstract
We report the results of a search for T, CP, and CPT violation in (B) over bar (0)-(B) over bar (0) mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II B factory. Using a sample of 232x10(6) B (B) over bar pairs, we measure the T and CP violation parameter vertical bar q/p vertical bar-1=(-0.8 +/- 2.7(stat)+/- 1.9(syst))x10(-3), and the CPT and CP parameters Imz=(-13.9 +/- 7.3(stat)+/- 3.2(syst))x10(-3) and Delta Gamma xRez=(-7.1 +/- 3.9(stat)+/- 2.0(syst))x10(-3) ps(-1). The statistical correlation between the measurements of Imz and Delta Gamma xRez is 76%.File in questo prodotto:
