Progress in the improved lattice calculation of direct CP-violation in the Standard Model


  • Dr. Christopher KELLY

Primary authors


We discuss the ongoing effort by the RBC & UKQCD collaborations to improve our lattice calculation of the measure of Standard Model direct CP violation, \epsilon', with physical kinematics. We present our progress in decreasing the (dominant) statistical error, which we aim to reduce by a factor of 2 within the next year, including a comparison of performance figures for our measurements on Intel KNL machines with differing networks and IBM Blue Gene/Q machines. We will also discuss other related activities aimed at reducing the systematic errors.
