摘要：

We present a calculation of the renormalization coefficients of the quark bilinear operators and the K - (K) over bar mixing parameter B-K. The coefficients relating the bare lattice operators to those in the RI/MOM scheme are computed nonperturbatively and then matched perturbatively to the (MS) over bar scheme. The coefficients are calculated on the RBC/UKQCD 2 + 1 flavor dynamical lattice configurations. Specifically we use a 16(3) x 32 lattice volume, the Iwasaki gauge action at beta = 2.13 and domain wall fermions with L-s = 16.
