Chiral symmetry breaking from Ginsparg-Wilson fermions
arXiv:hep-lat/9909026 · doi:10.1016/S0920-5632(00)91759-6
Abstract
We calculate the large-volume and small-mass dependences of the quark condensate in quenched QCD using Neuberger's operator. We find good agreement with the predictions of quenched chiral perturbation theory, enabling a determination of the chiral lagrangian parameter Σ, up to a multiplicative renormalization.
