Abstract
We report on a calculation of epsilon ' (K)/epsilon (K) at next-to-leading in the 1/N-c expansion and to lowest order in Chiral Perturbation Theory. W e discuss the short-distance matching, the scale and scheme dependence as w ell as the long-distance short-distance matching. We include the two known chiral corrections to our result and discuss further order p(4) corrections to it.
