Abstract: In order to enhance our understanding of spectral functions in lattice QCD
obtained with the help of the Maximum Entropy Method, we study meson spectral func-
tions for lattice fermions with chiral symmetry. In particular we analyse lattice artefacts
for standard overlap, overlap hypercube and domain wall fermions in the free field limit.
We also present first results for pseudoscalar spectral functions in dynamical QCD with
2 + 1 flavours of domain wall fermions, using data generated by the UKQCD and RBC
collaborations on QCDOC machines.
Keywords: Lattice Gauge Field Theories, Lattice QCD.
