Title: Finite volume effects in B{sub K} with improved staggered fermions

Abstract

We extend our recent unquenched (N{sub f}=2+1 flavor) calculation of B{sub K} using improved staggered fermions by including in the fits the finite volume shift predicted by one-loop staggered chiral perturbation theory. The net result is to lower the result in the continuum limit by 0.6%. This shift is slightly smaller than our previous estimate of finite volume effects based on a direct comparison between different volumes.
