Behind and Beyond the Standard Model - Day 5

Explore advanced concepts in particle physics through this comprehensive seminar lecture by Riccardo Rattazzi from EPFL Lusanne, focusing on the Standard Model and its extensions. Delve into three main segments: modern Effective Field Theory perspective on Quantum Field Theory, examining symmetries and naturalness in mass scale separations; analysis of the Standard Model's phenomenological adequacy and scale separation challenges; and investigation 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 tension between naturalness and simplicity in 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, and the Standard Model as an Effective Field Theory.
