Vector Meson Exchanges and CP Asymmetry in $K^{\pm}\rightarrowπ^{\pm}π^0$

Abstract

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