Description
We present preliminary results of a second, finer-lattice-spacing calculation of the I=0 K->pi pi decay amplitude in the 3 flavor theory with physical kinematics and G-parity boundary conditions, performed by the RBC & UKQCD collaborations. This new calculation will enable a continuum limit extrapolation, reducing/eliminating the significant finite-lattice spacing systematic error on our previous result. These measurements provide a Standard Model prediction for direct CP violation in kaon decays that is directly comparable to experiment.
