WebAug 22, 2015 · When discussing chiral perturbation theory it is implied that you are interested in low energy processes. If you are considering processes such as low energy (~100 MeV) pion scattering, pion decay, etc. then the typical energies involved are O(100 MeV) which is much smaller then $\Lambda_{QCD}$. WebCHIRAL PERTURBATION THEORY Gerhard Ecker Institut fur Theoretische Physik, Universitat Wien Boltzmanngasse 5, A-1090 Wien, Austria ABSTRACT After a general introduction to the structure of effective field theories, the main ingredients of chiral perturbation theory are reviewed. Applications include the light quark mass ratios
