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

Kjærgaard, L. and Mansfield, P. (1999) 'Calculating the infrared central charges for perturbed minimal models : improving the RG perturbation.', Physics letters B., 462 (1-2). pp. 103-108.


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.
