Im$A_0$, Im$A_2$, and ${\epsilon }^{\prime }$ from quenched lattice QCD

T. Blum, RBC Collaboration

We present results for the imaginary parts of the I=0 and 2 $K\to \pi \pi$ decay amplitudes, Im$A_{0,2}$, and the ratio of CP violation parameters, ${\epsilon }^{\prime }/\epsilon$. Our calculation is done…
