Description

We present results of ${\epsilon }_K$, the indirect CP violation parameter calculated on the lattice combined with various inputs from the experiments. In this analysis we use the lattice results of $B_K$ and $V_{cb}$ for the exclusive channel. In addition, we also use Wolfenstein parameters from the CKM fitters and UT fitters. We find 3.4(3) $\sigma$ difference in the exclusive $V_{cb}$ channel. We report details of this result.
