Chiral Limit Prediction for epsilon'/epsilon at NLO in 1/N_c

Abstract

We report on a calculation of ${\epsilon }_K^{\prime }/{\epsilon }_K$ at next-to-leading in 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 known chiral corrections to our result and discuss further order $p^4$ corrections to it.
