Spectral functions at non-zero momentum in hot QCD
  We present results for meson spectral functions at non-zero momentum at temperatures both below and above Tc, obtained in quenched simulations for a number of valence quark masses. For the lightest quark masses, a clear difference between the spectral functions on cold and hot lattices is observed.
