A renormalizable effective theory for leading logarithms in ChPT

High Energy Physics - Phenomenology 2008-11-26 v1

Abstract

We argue that the linear sigma model at small external momenta is an effective theory for the leading logarithms of chiral perturbation theory. Based on this assumption an attempt is made to sum these leading logarithms using the standard renormalization group techniques, which are valid in renormalizable quantum field theories.
