Behind and Beyond the Standard Model: Effective Field Theory and Extensions - Day 2

Explore advanced concepts in particle physics through this comprehensive seminar lecture by Riccardo Rattazzi from EPFL Lusanne, focusing on the theoretical foundations and extensions of the Standard Model. Delve into three main segments: first examining the modern Effective Field Theory perspective on Quantum Field Theory, including discussions on symmetries and naturalness in mass scale separations; second analyzing the Standard Model's phenomenological adequacy and scale separation challenges; and third investigating major extensions like Compositeness and Supersymmetry. Learn how these extensions address natural scale separation while creating tension between naturalness and simplicity in what's known as the hierarchy paradox. Examine the role of past, present, and future collider experiments in exploring these theoretical frameworks, while covering key topics such as RG-flow, selection rules, the Standard Model as an Effective Field Theory, and the complex relationship between naturalness and simplicity in particle physics theory.
