Query: Two-flavour lattice QCD correlation functions in the deconfinement
  transition region   We report on a lattice QCD calculation with two dynamical flavors of the
isovector vector correlator in the high-temperature phase. We analyze the
correlator in terms of the associated spectral function by performing a fit for
the difference of the thermal and vacuum spectral functions, using also an
exact sum rule that constrains this difference. Additonally we carry out a
direct fit for the thermal spectral function, and obtain good agreement between
the two analyses for frequencies below the two-pion threshold. Under the
assumption that the spectral function is smooth in that region, we give an
estimate of the electrical conductivity.
