Calculating the infrared central charges for perturbed minimal models: improving the RG perturbation

High Energy Physics - Theory 2009-10-31 v2 Statistical Mechanics

Abstract

We illustrate a method for improving Renormalisation Group improved perturbation theory by calculating the infrared central charge of a perturbed conformal field theory. The additional input is a dispersion relation that exploits analyticity of the energy-momentum tensor correlator.
