Description
We present the Standard Model evaluation of the indirect CP
violation parameter $\varepislon_K$ determined using lattice QCD
inputs: $\hat{B}_K$, $\xi_0$, $V_{us}$, and $V_{cb}$.
We find that the Standard Model prediction of $\varepsilon_K$ with
exclusive $V_{cb}$ (lattice QCD results) is lower than the experimental
value by $3.6\sigma$.
However, this tension disappears with inclusive $V_{cb}$ (results of
heavy quark expansion).
