Calculation of CP Violation in Non-leptonic Kaon Decay on the Lattice

Abstract

We give a progress report of our lattice calculation of direct and indirect CP violation in kaon decays, parametrized as ${ϵ}^{\prime }/ϵ$ and $B_K$, which require non-perturbative calculation of the matrix elements of the Standard Model effective Hamiltonian.
