Description

We analyse 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 ΔA_CP. We also make predictions for 𝛿_𝐾𝜋 and the branching fraction for the decay 𝐷⁺_𝑠→𝐾⁺𝐾_𝐿.
