چکیده

We compute the ratio ΛL/ΛMS between the scale parameter ΛL, associated with a lattice formulation of QCD using the overlap-Dirac operator, and ΛMS of the MS renormalization scheme. To this end, the necessary one-loop relation between the lattice coupling g0 and the coupling renormalized in the MS scheme is calculated, using the lattice background field technique.

Lattice Qcd with the Overlap-dirac Operator: Its Λ Parameter, and One-loop Renormalization of Fermionic Currents

We compute the ratio between the scale ΛL associated with a lattice formulation of QCD using the overlap-Dirac operator, and Λ MS . To this end, the one-loop relation between the lattice coupling g0 and the coupling renormalized in the MS scheme is calculated, using the lattice background field technique. We also compute the one-loop renormalization ZΓ of the two-quark operators ψ̄Γψ, where Γ de...

Localization of Low Lying Eigenmodes for Chirally Symmetric Dirac Operator

We consider properties of zero and near-zero modes for overlap fermion operator in SU(2) lattice gluodynamics. The density of the states is of the order of Λ QCD while the localization volume of the modes tends to zero in physical units with the lattice spacing tending to zero. The situation changes drastically when we study "vortex removed" configurations.

One-loop Analyses of lattice QCD with the overlap Dirac operator

We discuss the weak coupling expansion of lattice QCD with the overlap Dirac operator. The Feynman rules for lattice QCD with the overlap Dirac operator are derived and the quark self-energy and vacuum polarization are studied at the one-loop level. We confirm that their divergent parts agree with those in the continuum theory. PACS: 11.15.Ha

The order parameter of the chiral phase transition is directly related to the infrared part of the spectrum of the QCD Dirac operator. This part of the spectrum follows from the low energy limit of QCD which is given by a partition function of weakly interacting Goldstone modes. We find that the slope of the Dirac spectrum is determined by the pion decay constant whereas for λ ≪ 1/L 2 Λ QCD the...

Axial U(1) symmetry in the chiral symmetric phase of 2-flavor QCD at finite temperature

We discuss the fate of the axial U(1) symmetry in 2-flavor QCD at finite temperature, where the non-singlet chiral symmetry is restored. We first summarize the previous theoretical investigation on the relation between the eigenvalue density of the Dirac operator and the axial U(1) symmetry. We show that the eigenvalue density near the origin behaves as λ γ with γ > 2 in the chirally symmetric ...
