Recent results from systematic parameterizations of Ginsparg-Wilson fermions
The ”Fixed Point Dirac Operator” and ”Chirally Improved Fermions” both use large numbers of gauge paths and the full Dirac structure to approximate a solution of the Ginsparg-Wilson equation. After a brief review of the two approaches we present recent results for quenched QCD with pion masses down to 210 MeV. We discuss the limits and advantages of approximate parameterizations and outline fut...
متن کاملThe Hadron Spectrum from Lattice Qcd *
Determining the hadron spectrum and hadron properties beyond the ground states is a challenge in lattice QCD. Most of these results have been in the quenched approximation but now we are entering the dynamical era. I review some of the ideas and methods of the lattice approach, concentrating on a few examples and on results obtained for Chirally Improved (CI) fermions.
متن کاملRenormalization of bilinear quark operators for the chirally improved lattice Dirac operator
We compute non-perturbative renormalization constants of fermionic bilinears for the chirally improved lattice fermions in the quenched approximation of QCD. We address finite size effects and the influence of Gribov copies. Our results are presented in the RI’ and MS schemes as well as in RGI form and we discuss relations between the renormalization constants implied by chiral symmetry. PACS: ...
