Description
In 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.
Main topics:
- Introduction to Effective Field Theories
