Calculating $B_K$ using a mixed action

Abstract

We present preliminary results of $B_K$ calculated using improved staggered fermions with the mixed action (valence quarks = HYP staggered fermions and sea quarks = AsqTad staggered fermions). We analyze the data based upon the prediction by Van de Water and Sharpe. A hint of consistency with the prediction is observed. We also present preliminary results of $B_8^{(3/2)}$ and $B_7^{(3/2)}$.
