LehrspracheEnglisch


KurzbeschreibungThis course provides a comprehensive introduction to two advanced topics in Quantum Field Theory: Effective Field Theories (EFTs) and Supersymmetry (SUSY).
Lernziel
InhaltIn the first part we will discuss the basic concepts of EFTs, with particular attention to the concepts of decoupling of heavy degrees of freedom, matching and renormalization, chiral Lagrangians. The Standard Model viewed as an EFT will also be discussed as a specific application. The second part of the course is devoted to Supersymmetry, starting from the discussion of the SUSY algebra and its representations, to arrive, after the presentation of the superfield formalism, to the construction of the supersymmetric version of gauge field theories. A phenomenological discussion of the mechanisms of SUSY breaking and the construction of viable supersymmetric extensions of the Standard Model will also be presented.

Topics:

- Introduction to Effective Field Theories
- The Appelquist-Carrazone theorem
- The matching procedure
- Chiral Lagrangians
- The SM as an EFTs
- The SUSY algebra
- Superspace and superfields
- Supersymmetric field theories
- Supersymmetric gauge theories
- Supersymmetry breaking
- The Minimal supersymmetric Standard Model
