摘要：

We verify the QED Ward identity for the two- and three-point functions at non-equilibrium in the hard thermal loop (HTL) limit. We use the Keldysh formalism of real time finite temperature field theory. We obtain an identity of the same form as the Ward identity for a set of one loop self-energy and one loop three-point vertex diagrams which are constructed from HTL effective propagators and vertices.
