Abstract
We present a calculation of the renormalization coefficients of the quark bilinear operators and the $K\ensuremath{-}\overline{K}$ 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 $\overline{\mathrm{MS}}$ scheme. The coefficients are calculated on the RBC/UKQCD $2+1$ flavor dynamical lattice configurations. Specifically we use a ${16}^{3}\ifmmode\times\else\texttimes\fi{}32$ lattice volume, the Iwasaki gauge action at $\ensuremath{\beta}=2.13$ and domain wall fermions with ${L}_{s}=16$.
