Off-shell quark bilinear operator Green's functions at two loops
arXiv:1906.02116 · doi:10.1103/PhysRevD.99.125017
Abstract
We construct the two loop Green's functions for a quark bilinear operator inserted at non-zero momentum in a quark 2-point function for the most general off-shell configuration. In particular we consider the quark mass operator, vector and tensor currents as well as the second moment of the flavour non-singlet Wilson operator.
