Effective Field Theories I

Periodo di svolgimento

da Domenica, 31 Gennaio 2021 a Domenica, 30 Maggio 2021
Ore del corso: 20
Ore dei docenti responsabili: 20

Modalità d'esame

  • Prova orale

Prerequisiti

Il corso sarà rivolto agli allievi del IV Anno.

Prerequisiti necessari: Fisica Teorica 1

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 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.
