One-loop renormalization of fermionic currents with the overlap-Dirac operator
(2000)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 ...

λ-parameter of lattice QCD with the overlap-Dirac operator
(2000)We compute the ratio ΛL/Λ/MS between the scale parameter ΛL, associated with a lattice formulation of QCD using the overlap-Dirac operator, and Λ/MS of the MS renormalization scheme. To this end, the necessary one-loop ...
