Chiral dynamics of rare eta decays and virtual Compton scattering off the nucleon
S. Scherer
Abstract
Two different topics relevant for DAΦNE and CEBAF, respectively, are covered. First we analyze the rare radiative eta decay mode ηππγγ within the framework of chiral perturbation theory at O(p4). We then discuss virtual Compton scattering off the nucleon at low energies. Predictions for the two spin-independent generalized polarizabilities are shown.
