摘要：

The contribution of a K*(1430) 0(+) resonance to D-0 --> K(-)pi(+) is calculated by applying the soft pion theorem to D+ --> K*pi(+), and is found to be about 30% of the measured amplitude and to be larger than the Delta I = 3/2 component of this amplitude. We estimate a 70% contribution to the total amplitude from a higher K*(1950) resonance. This implies large deviations from factorization in D decay amplitudes, a lifetime difference between D-0 and D+, and an enhancement of D-0-(D) over bar(0) mixing due to SU(3) breaking.
