Resummation methods at finite temperature: The tadpole way.
نویسندگان
چکیده
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.

Renormalization and Resummation in Field Theories
Using resummation in perturbation theories at finite temperature or in nonequilibrium is unavoidable to obtain consistent results. Resummation, however, is often in conflict with renormalization. In this talk we give two possible solutions to problems of this type in static resummation. One is the use of auxiliary finite temperature UV divergent counterterms. The other is to use a renormalizati...
متن کاملRenormalization and resummation in finite temperature field theories
Resummation, ie. reorganization of perturbative series, can result in an inconsistent perturbation theory, unless the counterterms are reorganized in an appropriate way. In this paper two methods are presented for resummation of counterterms: one is a direct method where the necessary counterterms are constructed order by order; the other is a general one, based on renormalization group argumen...
متن کاملRenormalization in momentum dependent resummations
At finite temperature and in non-equilibrium environments we have to resum perturbation theory to avoid infrared divergences. Since resummation shuffles the perturbative orders, renormalizability is a nontrivial issue. In this paper we demonstrate that one can modify any type of resummations – even if it is momentum dependent, or it resums higher point functions – in a way that it is renormaliz...
متن کاملTransport Coefficients and Analytic Continuation in Dual 1 + 1 Dimensional Models at Finite Temperature
The conductivity of a finite temperature 1+1 dimensional fermion gas described by the massive Thirring model is shown to be related to the retarded propagator of the dual boson sine-Gordon model. Duality provides a natural resummation which resolves infra-red problems, and the boson propagator can be related to the fermion gas at non-zero temperature and chemical potential or density. In additi...
متن کاملResummation of Cactus Diagrams in the Clover Improved Lattice Formulation of QCD
We extend to the clover improved lattice formulation of QCD the resummation of cactus diagrams, i.e. a certain class of tadpole-like gauge invariant diagrams. Cactus resummation yields an improved perturbative expansion. We apply it to the lattice renormalization of some two-fermion operators improving their one-loop perturbative estimates.
