| dc.description | The classically perfect Fixed-Point fermion action for lattice QCD, a highly improved discretization of the continuum theory that preserves chiral symmetry, is constructed in this thesis and a parallel work by T. Jorg. In the framework of the BGR collaboration, we perform studies in quenched light hadron spectroscopy with this new action in order to examine its chiral and scaling properties and investigate in detail the chiral limit of pseudoscalar mesons. Topological finite-volume artifacts are identified and removed, and the coefficient of the quenched chiral logarithm is measured. The results show that the Fixed-Point action allows to simulate at quark masses corresponding to PS/V<0.3, has small scaling violations in hadron masses and reproduces the continuum energy-momentum dispersion relation very well. | |
