摘要：

A global previous analysis of two-body nonleptonic decays of D mesons has been extended to the decays involving light scalar mesons. The allowance for final state interaction also in nonresonant channels provides a fit of much improved quality and with less symmetry breaking in the axial charges. We give predictions for about 50 decay branching ratios yet to be measured. We also discuss long distance contributions to the difference Delta Gamma between the D-S and D-L widths.
