On the Origin of the Enhancementof CP-violating Charge Asymmetries in $K\to 3\pi$ Decays Predicted from Chiral Theory

Abstract

We present an analysis of the enhancement of CP-violating charge asymmetries in $K\to 3\pi$ decays. Calculations of decay amplitudes are performed on the basis of bosonized strong and weak Lagrangians derived from QCD-motivated quark Lagrangians. We show that the interplay of fourth-order contributions of chiral Lagrangians for strong interactions and penguin operators in weak interactions significantly enhances the charge asymmetries.
