Supersymmetric Grand Unified Theory Contributions and Model Independent Extractions ofCPPhases

Abstract
We consider the origin of new phases in the supersymmetric grand unification model, and show how significant new contributions arise from the gluino mediated diagram. We then present a more general model independent analysis of various modes of B decays suggested previously for measurement of the Cabibbo-Kobayashi-Maskawa phases and point out what they really measure. It is, in principle, possible to separate out all the phases.
