Effective Field Theories

Abstract

These lectures introduce some of the basic notions of effective field theories, as used in particle physics. The topics discussed are the $\Delta S=1$ and $\Delta S=2$ weak interactions, and chiral perturbation theory as applied to mesons, baryons, and hadrons containing heavy quarks.
