Zhang (RBC and UKQCD Collaborations) We report the first lattice QCD calculation of the complex kaon decay amplitude A 0 with physical kinematics, using a 32 3 × 64 lattice volume and a single lattice spacing a , with 1 / a = 1.3784 ( 68 ) GeV . We find Re ( A 0 ) = 4.66 ( 1.00 ) ( 1.26 ) × 1 0 − 7 GeV and Im ( A 0 ) = − 1.90 ( 1.23 ) ( 1.08 ) × 1 0 − 11 GeV , where the first erro… [Phys. Rev. Lett. 115, 212001] Published Tue Nov 17, 2015
