Description

The K+→π+π0γ and K0L,S→π+π-γ are reexamined in a simple chiral Lagrangian scheme. The inner bremsstrahlung part of the amplitude is well explained within a chiral Lagrangian approach supplemented by the 1/N expansion, while the direct emission term is generated by the effective Wess-Zumino term. The calculation of these terms does not affect the present knowledge of CP violating parameter in KL0→π+π-γ and also there is no implication on the K±→π±π0γ asymmetry parameter. (orig.)
