This course covers the basic concepts of effective field theories (EFTs) and quantum field theories beyond the Standard Model (SM). We will start by introducing the core concept of constructing EFTs and apply them to the SM Lagrangian.
In the next part of the course, we will discuss Chiral Perturbation Theory (ChPT), the low-energy effective theory of Quantum Chromodynamics (QCD). After this, the concept is applied to describe a class of theories beyond the SM, in which the SM Higgs arises as a composite state of a new confining sector.
For the remainder of the course, we will focus our attention to the concept of Supersymmetry (SUSY), starting from the discussion of the SUSY algebra and its representations, to arrive, after the presentation of the superspace formalism, to the construction of the supersymmetric version of gauge field theories
