Abstract

New data on the decays of the charmed particles D⁰, D⁺, and D_s⁺ to pairs of light pseudoscalar mesons P allow the testing of flavor symmetry and the extraction of key amplitudes. Information on relative strong phases is obtained. One sees evidence for the expected interference between Cabibbo-favored and doubly Cabibbo-suppressed decays in the differing patterns of D⁰\ensuremath→K_S,L\ensuremathπ⁰ and D⁺\ensuremath→K_S,L\ensuremathπ⁺ decays.
