摘要：

We calculate the three-dimensional QED (QED3) photon polarization tensor using dressed fermion propagators and a fermion-photon vertex that satisfies the Ward-Takahashi identity. Irrespective of the structural details of the transverse part of the fermion-photon vertex the photon remains massless; i.e., there is no photon mass generation in the manner of the Schwinger mechanism. Our calculation suggests that QED3 is confining when the polarization tensor is calculated using a dressed fermion propagator and fermion-photon ver-tex. The gauge parameter dependence of the fermion propagator, fermion-photon vertex, and photon polarization tensor is discussed in connection with the Landau-Khalatnikov gauge transformation laws.
