Vector Meson Exchanges and CP Asymmetry in $K^{\pm }\to {\pi }^{\pm }{\pi }^0$

Abstract

Using a current algebra framework, we discuss the contribution of vector meson exchanges to the CP violating asymmetry in the decay $K^{\pm }\to {\pi }^{\pm }{\pi }^0$, resulting from the interference of the $K\to \pi \pi$ amplitude with the radiative correction $K\to \pi \pi \gamma$.
