dc.descriptionA self-consistent analysis of K->2pi and K->3pi decays within a unique framework of chiral dynamics applied to the QCD-corrected weak nonleptonic quark lagrangian has been performed. The results on K->2pi amplitudes at O(p^6), including the value for epsilon'/epsilon, are compared with the experiment to fix phenomenological B-factors for mesonic matrix elements of nonpenguin and penguin four-quark operators. The dependence of B-factors on different theoretical uncertainties and experimental errors of various input parameters is investigated. Finally, we present our estimates at O(p^6) for the CP-asymmetry of linear slope parameters in the K(+-)->3pi Dalitz plot.
