Abstract: We calculate corrections to the fermion propagator and to the Green's functions of all fermion bilinear operators of the form PsibarGammaPsi, to one-loop in perturbation theory. We employ the Wilson/clover action for fermions and the Symanzik improved action for gluons. The novel aspect of our calculations is that they are carried out to second order in the lattice spacing, O(a^2). Consequently, they have addressed a number of new issues, most notably the appearance of loop integrands with stron
