Analytic Form of the One-loop Vertex and of the Two-loop Fermion Propagator in 3-Dimensional Massless QED

A. Bashir, A. Kizilersu, M. R. Pennington

We evaluate the analytic expression for the one-loop fermion-boson vertex in massless QED3 in an arbitrary covariant gauge. The result is written in terms of elementary functions o…
