Phenomenological analysis of epsilon'/epsilon within an effective chiral lagrangian approach at O(p^6)
arXiv:hep-ph/9907335
Abstract
We have combined a new systematic calculation of mesonic matrix elements at O(p^6) from an effective chiral lagrangian approach with Wilson coefficients taken from paper by G.Buchalla et al. Rev.Mod.Phys. 68 (1996) 1125, derived in the framework of perturbative QCD, and restricted partly by experimental data. We derive complete expressions for K-->2pi amplitudes and compare the results for epsilon'/epsilon with experiment.
