摘要
A previous analysis of two-body Cabibbo-allowed nonleptonic decays of D0 mesons and of Cabibbo-allowed and first-forbidden decays of D+ and Ds+ has been adjourned using more recent experimental data and extended to the Cabibbo-forbidden decays of D0. Annihilation and W-exchange contributions as well as final state interaction effects (assumed to be dominated by nearby resonances) have been included and are in fact crucial to obtain a reasonable agreement with the experimental data, which show large flavor SU(3) violations. New fitting parameters are necessary to describe rescattering effects for Cabibbo-forbidden D0 decays, given the lack of experimental information on isoscalar resonances. We keep their number to a minimum, three, using phenomenologically based considerations. We also discuss CP-violating asymmetries. © 1995 The American Physical Society.
