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