Testing chiral effective theory with quenched lattice QCD
We investigate two-point correlation functions of left-handed currents computed in quenched lattice QCD with the Neuberger-Dirac operator. We consider two lattice spacings a ≃ 0.09, 0.12 fm and two different lattice extents L ≃ 1.5, 2.0 fm; quark masses span both the pand the ǫ-regimes. We compare the results with the predictions of quenched chiral perturbation theory, with the purpose of testi...
متن کاملQuenched chiral logarithms in lattice QCD with exact chiral symmetry
We examine quenched chiral logarithms in lattice QCD with overlap Dirac quark. For 100 gauge configurations generated with the Wilson gauge action at β = 5.8 on the 83 × 24 lattice, we compute quenched quark propagators for 12 bare quark masses. The pion decay constant is extracted from the pion propagator, and from which the lattice spacing is determined to be 0.147 fm. The presence of quenche...
متن کاملEffective Theory for Quenched Lattice QCD and the Aoki Phase
We discuss the symmetries of quenched QCD with Wilson fermions, starting from its lagrangian formulation, taking into account the constraints needed for convergence of the ghost-quark functional integral. We construct the corresponding chiral effective lagrangian, including terms linear and quadratic in the lattice spacing. This allows us to study the phase structure of the quenched theory, and...
