Renormalization of Bilinear Quark Operators for Overlap Fermions
arXiv:hep-lat/0507017 · doi:10.1103/PhysRevD.72.054508
Abstract
We present non-perturbative renormalization constants of fermionic bilinears on the lattice in the quenched approximation at beta=6.1 using an overlap fermion action with hypercubic(HYP)-blocked links. We consider the effects of the exact zero modes of the Dirac operator and find they are important in calculating the renormalization constants of the scalar and pseudoscalar density. The results are given in the RI' and MS bar schemes and compared to the perturbative calculations.
