摘要: Abstract We present the first set of quenched QCD measurements using recently parametrized fixed-point Dirac operator D FP . also give a general and practical construction covariant densities conserved currents for chiral lattice actions. The include (a) hadron spectroscopy, (b) corrections small deviations, (c) renormalized quark condensate from finite-size scaling and, independently, (d) topological susceptibility, (e) eigenvalue distributions random matrix theory, (f) local chirality near-zero modes instanton-dominance.
