摘要
The contribution of a resonance to is calculated by applying the soft pion theorem to , and is found to be about 30% of the measured amplitude and to be larger than the component of this amplitude. We estimate a 70% contribution to the total amplitude from a higher resonance. This implies large deviations from factorization in D decay amplitudes, a lifetime difference between D^0 and D^+, and an enhancement of mixing due to SU(3) breaking.
