One-loop renormalization of fermionic currents with the overlap-Dirac operator

Abstract

We compute the one-loop lattice renormalization of the two-quark operators ψ̄Γψ, where Γ denotes the generic Dirac matrix, for the lattice formulation of QCD using the overlap-Dirac operator. We also study the renormalization of quark bilinears which are more extended and have better chiral properties. Finally, we present improved estimates of these… (More)
