Renormalization of bilinear quark operators for the chirally improved lattice Dirac operator

Zusammenfassung

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) over bar schemes as well as in RGI form and we discuss relations between the renormalization constants implied by chiral symmetry. (C) 2004 Elsevier B.V.
