Unitarized chiral perturbation theory of hadrons

Nuclear Theory 2009-11-07 v1

Abstract

An exposition is made of recent developments using techniques of unitary chiral perturbation theory, UχPTU \chi P T, which allows one to extend predictions using chiral Lagrangians to higher energies than ordinary chiral perturbation theory, including the region of low lying mesonic and baryonic resonances, some of which are dynamically generated in the approach. Results for meson meson scattering, pion and kaon form factors and meson baryon scattering are shown. Applications are done for nuclear problems showing the results for the kaon and eta selfenergies, phi renormalization in a nuclear medium and σ\sigma renormalization in the medium, comparing results with recent experiments.
