用RI/Sunday和RI/Sunday方案计算了味畴壁费米子组态上重叠夸克双线性算符的重整化常数。轴向矢量流的尺度无关RC通过使用Ward恒等式计算。然后计算了夸克场和矢量、张量、标量和赝标量算符的RCs，并给出了RI/SRI和RI/SRI两种方案的计算结果。将RC格式转化为该格式，并比较了两种中间格式的数值结果。晶格尺寸与间距成反比.
Renormalization constants (RCs) of overlap quark bilinear operators on-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 thescheme and we compare the numerical results from using the two intermediate schemes. The lattice size isand the inverse spacing.
