英文摘要	We present renormalization constants of overlap quark bilinear operators on 2 + 1-flavor domain wall fermion configurations. This setup is being used by the chi QCD Collaboration in calculations of physical quantities such as strangeness in the nucleon and the strange and charm quark masses. The scale-independent renormalization constant for the axial-vector current is computed using the Ward identity. The renormalization constants for scalar, pseudoscalar, and vector currents are calculated in the RI-MOM scheme. Results in the (MS) over bar scheme are also given. The step scaling function of quark masses in the RI-MOM scheme is computed as well. The analysis uses, in total, six different ensembles of three sea quarks, each on two lattices with sizes 24(3) x 64 and 32(3) x 64 at spacings a = (1.73 GeV)(-1) and (2.28 GeV)(-1), respectively.
