Description/Abstract

We present a calculation of the renormalization coefficients of the quark bilinear operators and the K-K̅ mixing parameter BK. The coefficients relating the bare lattice operators to those in the RI/MOM scheme are computed nonperturbatively and then matched perturbatively to the MS̅ scheme. The coefficients are calculated on the RBC/UKQCD 2+1 flavor dynamical lattice configurations. Specifically we use a 163×32 lattice volume, the Iwasaki gauge action at β=2.13 and domain wall fermions with Ls=16.
