Behind and Beyond the Standard Model - Day 3

Explore advanced concepts in particle physics through this seminar lecture by Riccardo Rattazzi from EPFL Lusanne, focusing on the third day of discussions about the Standard Model and its extensions. Delve into three main areas: the modern Effective Field Theory perspective on Quantum Field Theory, including symmetries and naturalness concepts; an analysis of the Standard Model's phenomenological adequacy and scale separation; and an examination of Compositeness and Supersymmetry as primary extensions of the Standard Model. Learn how these extensions affect the Standard Model's structural simplicity and require specific model building hypotheses, creating a paradox between naturalness and simplicity. Understand the role of past, present, and future collider experiments in exploring these theoretical frameworks, while covering key topics such as RG-flow, selection rules, and the hierarchy paradox in particle physics.
