Abstract

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