Renorm-group, Causality and Non-power Perturbation Expansion in QFT
Abstract The structure of the QFT expansion is studied in the framework of a new “Causal analytic version” of the perturbation theory. Here, the leading idea is to combine the renormalization group (RG) invariance with a general property of causality expressed in the form of the Q2–analyticity. This combining is performed by a special procedure, “analytization”. The procedure, first proposed in...
متن کاملOn Renormalization Group in Abstract QFT
The basics of RG equations for generic partition functions are briefly reviewed, keeping in mind an application to the Polyakov-de Boer-Verlindes description of the holomorphic RG flow. 1 RG versus (generalized) Laplace equations The notion and properties of the (generalized) renormalization group (RG) [1, 2, 3] acquire a new attention last years, primarily because of the interest to its hidden...
متن کاملRenormalization-Group-improved perturbation theory
A method for computing the low-energy non-perturbative properties of SUSY GFT, starting from the microscopic lagrangian model, is presented. The method relies on covariant SUSY Feynman graph techniques, adapted to low energy, and RenormalizationGroup-improved perturbation theory. We apply the method to calculate the glueball superpotential in N = 1 SU(2) SYM and obtain a potential of the Venezi...
متن کاملRenormalization group method and canonical perturbation theory
Abstract. Renormalization group method is one of the most powerful tool to obtain approximate solutions to differential equations. We apply the renormalization group method to Hamiltonian systems whose integrable parts linearly depend on action variables. We show that the renormalization group method gives the same approximate solutions as canonical perturbation theory up to the second order of...
متن کاملPerturbation theory and renormalization group equations
Renormalization group ~RG! methods are an essential ingredient in the study of nonperturbative problems in continuum and lattice formulations of quantum field theory. A number of RG equations have been proposed, where the starting point is the ~infrared! regularized one-loop effective action. Taking the derivative with respect to the infrared scale together with a subsequent one-loop improvemen...
