Abstract
We report a precise determination of the [Formula Presented] mixing parameter [Formula Presented] based on the time evolution of same-sign and opposite-sign dilepton yields in [Formula Presented] decays. Data were collected with the Belle detector at KEKB. Using data samples of 29.4 [Formula Presented] recorded at the [Formula Presented] resonance and 3.0 [Formula Presented] recorded at an energy 60 MeV below the resonance, we measure [Formula Presented] From the same analysis, we also measure the ratio of charged and neutral B meson production at the [Formula Presented] [Formula Presented] and CPT violation parameters in [Formula Presented] mixing, [Formula Presented] and [Formula Presented..
