Mini-Lecture on Chiral Perturbation Theory, Part 2

This series of two different lectures will provide a pedagogical introduction to the basic concepts of Chiral Perturbation Theory (ChPT) and some applications. ChPT provides a systematic and model-independent approximation to quantum chromodynamics (QCD) at energies well below typical hadron masses. At these low energies QCD is nonperturbative and the relevant degrees of freedom are composite hadrons instead of the more fundamental quarks and gluons. ChPT is a low energy effective field theory formulated in terms of mesons and baryons, and is based on the symmetries of QCD and general principles of quantum field theory. I will discuss how ChPT is constructed and discuss applications in the meson and baryon sectors.
