摘要：
We show that Delta I = 3/2 transitions for quark W-emission K-2 pi diagrams and independently the current algebra-PCAC consistency scheme for all three K-2 pi amplitudes are extremely accurate, within 3% of the data. Although the same analysis applied to D-2 pi decays roughly approximates recent experiments, the agreement is only valid to within 25%-40% of the data.
