$\hat{I}”I=1/2$ process of $K\to \ddot{I}€\ddot{I}€$ decay on multiple ensembles with periodic boundary conditions

Masaaki Tomii

We present our preliminary results for the $\hat{I}”I=1/2$ matrix elements of $K\to \ddot{I}€\ddot{I}€$ decay and ${\epsilon }^{\prime }$, the measure of direct $CP$ violation in $K\to \ddot{I}€\ddot{I}€$, computed on multi…
