Abstract: On the basis of a next-to-leading-order calculation in chiral perturbation theory, the first complete analysis of isospin breaking for direct CP violation in K0→2π decays is performed. We find a destructive interference between three different sources of isospin violation in the CP violation parameter epsilon'. Within the uncertainties of large-Nc estimates for the low-energy constants, the isospin violating correction for epsilon' is below 15%.
