Resummation Methods at Finite Temperature: The Tadpole Way
C. Glenn Boyd, David E. Brahm, Stephen D. H. Hsu
Abstract
We examine several resummation methods for computing higher order corrections to the finite temperature effective potential, in the context of a scalar ϕ4 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.
