Scientific paper

The measurement of epsilon'/epsilon has left open several theoretical problems, the most important of which is an accurate calculation of the relevant hadronic matrix elements. Here we study the possibility of relating epsilon' to CP violation in charged K-> 3 pi, which can provide information on the reliability of such calculations. We discuss the role of final state interactions and the main sources of uncertainties. We find that the measurement of Delta g_C in K-> 3 pi is a crucial consistency test for the Standard Model calculations of epsilon'. Valuable information can be deduced also from other observables.
