摘要：

The CP violating asymmetry [Γ(K+→π+π0) - Γ(K-→π-π0)] / [Γ(K+→π+π0)+Γ(K-→π-π0)] due to isospin breaking effects is estimated. It is found that the dominant contribution to the asymmetry comes from an electromagnetic correction to the weak amplitude, yielding a value of order 10-6. Isospin breaking terms due to quark masses do not contribute to the asymmetry. © 1990.
