Behind and Beyond the Standard Model - Day 4

Explore advanced concepts in particle physics through this seminar lecture by Riccardo Rattazzi from EPFL Lusanne, focusing on the fourth day of discussions about what lies behind and beyond the Standard Model. Delve into three main segments: modern Effective Field Theory and its relationship to Quantum Field Theory, analysis of the Standard Model's phenomenological adequacy and scale separation challenges, and examination of major Standard Model extensions including Compositeness and Supersymmetry. Learn about the complex interplay between naturalness and simplicity in particle physics, understand the hierarchy paradox, and discover how past, present, and future collider experiments contribute to our understanding of these fundamental concepts. Master key topics including Effective Field Theory perspectives, RG-flow, symmetries, selection rules, naturalness, and the structural implications of Standard Model extensions through detailed theoretical frameworks and experimental evidence.
