| dc.description | We present a status report on our study of long-distance contributions to the decay amplitudes A(K^0 --> pi pi, I) in the framework of the 1/N expansion. We argue that a modified prescription for the identification of meson momenta in the chiral loop corrections has to be used to gain a self-consistent picture which allows an appropriate matching with the short-distance part. Possible uncertainties in the analysis of the density-density operators Q_6 and Q_8 which dominate the CP violation parameter epsilon'/epsilon are discussed. As a first result we present the long-distance 1/N correction to the gluon penguin operator Q_6 in the chiral limit. | |
