Quenched 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 کاملEstimate of the chiral condensate in quenched lattice QCD
We determine the value of the quark condensate from quenched QCD simulations on the lattice in two ways: (i) by using the Gell-Mann–Oakes–Renner (GMOR) formula; (ii) by comparing the OPE prediction for the Goldstone pole contribution to the pseudoscalar vertex, at moderately large momenta. In the MS scheme at μ = 2 GeV, from the GMOR formula we obtain 〈q̄q〉 = − (273± 19 MeV). We show that the va...
متن کاملPentaquark baryons in quenched lattice QCD with exact chiral symmetry
We investigate the mass spectrum of pentaquark baryons in quenched lattice QCD with exact chiral symmetry. Using interpolating operators based on the diquark-diquark-antiquark picture in the Jaffe-Wilzcek model, we measure time correlation functions for 70 gauge configurations generated with Wilson gauge action at β = 6.1 on the 203 × 40 lattice, and extract the masses of even and odd parity st...
متن کاملQuenched chiral logarithms in lattice QCD with overlap Dirac quarks ∗ †
We examine quenched chiral logarithms in lattice QCD with overlap Dirac quarks. From our data of m π , we determine the coefficient of quenched chiral logarithm δ = 0.203(14), 0.176(17), 0.193(17) and 0.200(13) for lattices of sizes 8 × 24, 10 × 24, 12 × 24 and 16 × 32 respectively. Also, for the first three lattice sizes, we measure the index susceptibility of the overlap Dirac operator, and u...
