Abstract

We study the lattice spacing dependence of meson spectral functions calculated in quenched QCD with domain wall fermions as well as clover Wilson fermions in quenched and partially-quenched QCD. We conclude that for lattice spacing $a \le 3$ GeV all excited states appearing in the spectral functions are lattice artifacts.
