Description
We discuss recent progress by the RBC & UKQCD collaborations in the lattice calculation of the measure of Standard Model direct CP violation, \epsilon', with physical kinematics. We present results with improved systematic errors resulting from the use of step-scaling to
reduce the renormalization error, an analysis that also takes into account the one-loop-suppressed mixing with the G_1 two-quark operator. We also review our progress in decreasing the dominant statistical error on our result.
