Determination of $B_K$ using improved staggered fermions (IV) One-loop matching

Abstract

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