Abstract

We discuss the impact of using one-loop matching on the calculation of BKB_K using HYP-smeared improved staggered fermions. We give estimates of size of the truncation errors from the missing two-loop corrections.

Keywords

BK parameter improved staggered fermions one-loop matching truncation errors two-loop corrections
