Calculation of $K\to \pi \pi$ decay amplitudes with improved Wilson fermion in 2+1 flavor lattice QCD

N. Ishizuka, K. I. Ishikawa, A. Ukawa +1

We present results for the $K\to \pi \pi$ decay amplitudes for both the $\Delta I=1/2$ and $3/2$ channels. This calculation is carried out on 480 gauge configurations in $N_f=2+1$ QCD generate…
