Query: Chiral symmetry restoration and deconfinement in QCD at finite
  temperature   The light-quark correlator in the axial-vector channel is used, in
conjunction with finite energy QCD sum rules at finite temperature, in order to
(a) establish a relation between chiral-symmetry restoration and deconfinement,
and (b) determine the temperature behavior of the $a_1(1260)$ width and
coupling. Results indicate that deconfinement takes place at a slightly lower
temperature than chiral-symmetry restoration, although this difference is not
significant given the accuracy of the method. The behaviour of the $a_1(1260)$
parameters is consistent with quark-gluon deconfinement, as the width grows and
the coupling decreases with increasing temperature.
