Description
The RBC & UKQCD collaborations have recently published lattice results for the K->pi pi decay amplitude in the I=2 channel, A_2, and improved results will be presented at this conference. In this presentation we discuss the determination of the I=0 channel amplitude, A_0. Combining this with A_2 provides epsilon', the measure of direct CP-violation in the Standard Model. In part I we provide an overview of the project and detail our use of G-parity boundary conditions to achieve physical kinematics in the decay, as well as discussing the ongoing generation of the specialized lattices required.
