Prerequisites

The course is aimed at 4th year master students.

Prerequisite: an introductory course on Quantum Field Theory.

 

Programme

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

Educational aims

The aim is to introduce the modern approach to quantum Effective Field Theories (EFTs). By the end of the course, students will know how to construct and use them. Moreover, they will learn why EFTs today play an ubiquitous role in theoretical physics by inspecting several examples ranging from the Standard Model of particle physics to gravity and the cosmology of the early universe.
