  The temporal pseudoscalar meson correlation function in a QCD plasma is
investigated in a range of temperatures exceeding $T_c$ and first time for a
finite momenta which is of the experimental interest. The imaginary time
formalism is employed for the finite temperature calculations. The behavior of
the meson spectral function and of the temporal correlator is studied in the
HTL approximation, where one replaces the free thermal quark propagators with
the HTL resumed ones.
