TL;DR

This paper calculates epsilon'/epsilon using next-to-leading order in 1/N_c expansion and lowest order Chiral Perturbation Theory, including known chiral corrections, to improve understanding of CP violation in kaon decays.

Contribution

It provides a novel calculation of epsilon'/epsilon at next-to-leading order in 1/N_c and lowest order in Chiral Perturbation Theory, incorporating known chiral corrections.

Findings

Calculated epsilon'/epsilon at next-to-leading order in 1/N_c

Included two known chiral corrections in the analysis

Discussed the impact of chiral corrections on the results

Abstract

We report on a calculation of epsilon'/epsilon at next-to-leading in the 1/N_c expansion and to lowest order in Chiral Perturbation Theory. We also discuss the chiral corrections to our results and give the result of including the two known chiral corrections.
