We present a non-perturbative determination of the renormalization factor ZS of the scalar density in quenched QCD with overlap fermions. Results are obtained at four values of the lattice spacing.… Expand

We calculate corrections to the fermion propagator and to the Green's functions of all fermion bilinear operators of the form , to one-loop in perturbation theory. We employ the Wilson/clover action… Expand

Abstract
We aim to show the effects of the magnetic monopoles and instantons in quantum chromodynamics (QCD) on observables; therefore, we introduce a monopole and anti-monopole pair in the QCD… Expand
