Effective Field Theories I
Prerequisiti
The course is aimed at 4th year master students.
Prerequisite: an introductory course on Quantum Field Theory.
Programma
The building blocks of the Standard Model
Representations of the Lorentz group: Particles vs Fields
Long range forces: gauge invariance from Lorentz invariance
Effective Field Theories and Renormalisation
The electroweak chiral Lagrangian and the Higgs boson
Obiettivi formativi
The objective of this course is to provide an introduction to the contemporary methodology of quantum Effective Field Theories (EFTs). Upon completion of the course, students will possess the knowledge and skills required to construct and utilize EFTs. Additionally, they will learn why EFTs today play an ubiquitous role in theoretical physics through the examination of various examples, including the Standard Model of particle physics, gravity, and the cosmology of the early universe.
