Resummation Methods at Finite Temperature: The Tadpole Way

High Energy Physics - Phenomenology 2011-07-19 v1

Abstract

We examine several resummation methods for computing higher order corrections to the finite temperature effective potential, in the context of a scalar ϕ4\phi^4 theory. We show by explicit calculation to four loops that dressing the propagator, not the vertex, of the one-loop tadpole correctly counts ``daisy'' and ``super-daisy'' diagrams.
