Prerequisiti

Prerequisiti necessari: Fisica Teorica 1, Effective Field Theories modulo I

Programma

General Relativity as an Effective Field Theory 

Renormalization Group flows, fixed points and critical surfaces

The naturalness of the electroweak scale

Spontaneous Symmetry Breaking and the Goldstone Theorem

The Callan-Coleman-Wess-Zumino formalism

Non-linear realization of space-time symmetries

The Effective Field Theory of Inflation

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.
