Abstract
A general analysis for B decays to two pseudoscalars, involving ten modes, is presented. A simple model for final state interactions and rescattering effects is proposed. We show how the data can be used to deduce important information on electroweak penguins (EWP), rescattering and color suppression effects and on the CKM parameters in a largely model independent way by using chisquared-minimization. We find that the current data suggests the presence of color-suppressed tree at levels somewhat larger than simple theoretical estimates. Once the data improves the extraction of alpha and/or gamma may become feasible with this method as we illustrate with the existing data.
In this version we have (1) clairified the relationship of our model with SU(3) identities (2)Used updated CLEO data (3)The correlation of electroweak penguins color suppressed tree and rescattering effects to individual modes is more clearly explained
