The course provides an introduction to effective-field-theory methods, which are widely used across various areas of particle physics. It begins by presenting the fundamental formalism, including mode separation, power counting and renormalisation-group techniques, and subsequently focuses on selected applications that are particularly relevant to the research activities pursued in the “Color meets Flavor” (CmF) excellence cluster.
