Effective Field Theories for Hadrons and Nuclei

Abstract

Hadron structure and nuclear structure are discussed from the common ground of effective chiral Lagrangians modeling QCD at low energy. The topics treated are the chiral bag model in large $N_c$ QCD, its connection to heavy-baryon chiral perturbation theory (HB\chpt),\ the role of nonabelian Berry gauge connections for baryon excitations and the application of HB\chpt \ to the thermal $n+p\to d+\gamma$ process and to the axial-charge transitions in heavy nuclei.
