Spectral density of the Hermitean Wilson Dirac operator: a NLO computation in chiral perturbation theory
We compute the lattice spacing corrections to the spectral density of the Hermitean Wilson Dirac operator using Wilson Chiral Perturbation Theory at NLO. We consider a regime where the quark mass m and the lattice spacing a obey the relative power counting $ m \sim a\Lambda_{\text{QCD}}^2 $ : in this …
