Symmetric point flavor singlet axial vector current renormalization at two loops

We calculate the two loop correction to the quark 2-point function with the nonzero momentum insertion of the flavor singlet axial vector current at the fully symmetric subtraction point for massless quarks in the modified minimal subtraction ((MS) over bar) scheme. The Larin method is used to handle gamma(5) within dimensional regularization at this loop order ensuring that the effect of the chiral anomaly is properly included within the construction.
