I discuss our recent publication [arXiv:2004.09440] of a lattice QCD calculation of the ΔI=1/2, K→ππ decay amplitude A0 and ?′, the measure of direct CP-violation in K→ππ decay. This quantity is highly sensitive to new sources of CP violation that might help to explain the matter/antimatter asymmetry in the observable Universe. This calculation dramatically improves on our 2015 results [Phys.Rev.Lett. 115 (2015) 21, 212001], including nearly four times the statistics and numerous technical improvements allowing us to more reliably isolate the ππ ground-state and more accurately relate the lattice operators to those defined in the Standard Model.
