Flavor mixing and mixing-induced CP violation in the neutral B system

We describe a new technique for measurements of mixing-induced CP violation in the $Bd$ system, wherein the decay time of only one B meson is measured. We find that excellent decay-point measurement resolution, high-efficiency meson flavor tagging, and precise knowledge of the B 0-$B0$ mixing parameters are required to carry out the experiment. We report on each of these aspects using the data collected by the CLEO experiment at the Cornell Electron Storage Ring. We present methods for assessing the performance and systematic uncertainties of a silicon vertex detector. We present assessments of the detector installed in the CLEO experiment. We present a method for high-efficiency B flavor tagging, and a measurement of its power. Using hadronic decays based on a method introduced by Nelson, Nelson, and Witherell, we present a new measurement of B0 -$B0$ mixing. This method has much reduced systematic uncertainties compared to previous measurements.
