Description
We present new results on the reconstruction of mesonic spectral functions for
three temperatures above T_c in quenched QCD. Making use of Clover improved
Wilson valence quarks allows for a clean extrapolation of correlator data to
the continuum. For the case of vanishing momentum the spectral function is
obtained by fitting the data to a well motivated ansatz. In the vector channel
for light quarks the electrical conductivity of the hot medium, related to the
origin of the spectral function at zero momentum, is computed from the
resulting parameters at all three temperatures.
