A Possible Higher Order Correction to the chiral Vortical Conductivity   in a Gauge Field Plasma
  The two loop contributions to the chiral vortical conductivity are considered. The Kubo formula together with the anomalous Ward identity of the axial vector current suggest that there may be a nonzero correction to the coefficient of the $T^2$ term of the conductivity.
