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