Systematic Resummed Perturbation Theory
A systematic loop expansion is formulated in terms of full propagators and vertices. It is based on an expansion of the general solution of an exact non-perturbative flow equation.
متن کاملAnalytical continuation and resummed perturbation theory
A pattern of partial resummation of perturbation theory series inspired by analytical continuation is discussed for some physical observables. Talk given at QCD 97 Conference, Montpellier, France 4 – 9 July 1997
متن کاملResummed thermodynamic perturbation theory for bond cooperativity in associating fluids.
We develop a resummed thermodynamic perturbation theory for bond cooperativity in associating fluids by extension of Wertheim's multi-density formalism. We specifically consider the case of an associating hard sphere with two association sites and both pairwise and triplet contributions to the energy, such that the first bond in an associated cluster receives an energy -ε((1)) and each subseque...
متن کاملHd{thep{96{2 Systematic Resummed Perturbation Theory
A systematic loop expansion is formulated in terms of full propagators and vertices. It is based on an expansion of the general solution of an exact non-perturbative ow equation. One-particle irreducible vertices are the basic building blocks for the computation of cross sections and decay rates in particle physics or for the critical equation of state in statistical physics. They are often com...
متن کاملSoft photon production rate in resummed perturbation theory of high temperature QCD
We calculate the production rate of soft real photons from a hot quark-gluon plasma using Braaten-Pisarski's perturbative resummation method. To leading order in the QCD coupling constant 9 we find a logarithmically divergent result for photon energies of order 9T, where T is the plasma temperature. This divergent behaviour is due to unscreened mass singularities in the effective hard thermal l...
