Renormalization constants (RCs) of overlap quark bilinear operators on 2 þ 1-flavor domain wall fermion configurations are calculated by using the RI/MOM and RI/SMOM schemes. The scale independent RC for the axial vector current is computed by using a Ward identity. Then the RCs for the quark field and the vector, tensor, scalar, and pseudoscalar operators are calculated in both the RI/MOM and RI/SMOM schemes. The RCs are converted to the MS scheme and we compare the numerical results from using the two intermediate schemes. The lattice size is 48 3 × 96 and the inverse spacing 1=a ¼ 1.730ð4Þ GeV.
