SU (3)F breaking through final state interactions and CP asymmetries in D→PP decays

Abstract

We analyze D decays to two pseudoscalars (π,K) assuming the dominant source of SU(3)F breaking lies in final state interactions. We obtain an excellent agreement with experimental data and are able to predict CP violation in several channels based on current data on branching ratios and ΔACP. We also make predictions for δKπ and the branching fraction for the decay Ds+←K+KL.
