Detailed Description

A class for \(\epsilon_K\) that parametrizes indirect CPV in the Kaon sector.

This class is used to compute the theoretical value of \(\epsilon_K\). This parameter gets contributions both from the SM and many NP models. It is an important constraint on FCNC from NP models, specially those contributing to chirality flipping \(\Delta F = 2\) operators due to large enhancement by QCD running of these operators to Koan mass scales.
