A Maximally Symmetric Vector Propagator
N. C. Tsamis, R. P. Woodard
We derive the propagator for a massive vector field on a de Sitter background of arbitrary dimension. This propagator is de Sitter invariant and possesses the proper flat spacetime…

Two Loop Scalar Bilinears for Inflationary SQED
T. Prokopec, N. C. Tsamis, R. P. Woodard
We evaluate the one and two loop contributions to the expectation values of two coincident and gauge invariant scalar bilinears in the theory of massless, minimally coupled scalar…
