Positivity Constraints on Effective Field Theories - Lecture 1

Explore the fundamental concepts of positivity constraints on Effective Field Theories (EFTs) in this comprehensive lecture by Brando Bellazzini. Delve into the first part of a series focusing on low-energy EFTs, presented as part of the School for Advanced Topics in Particle Physics (SATPP) at the International Centre for Theoretical Sciences. Gain insights into the systematic approach of describing physics at different scales using relevant degrees of freedom, and understand how EFTs have become essential tools in understanding our universe. Learn about the application of EFTs in describing unknown phenomena at the TeV scale and above, as well as their role in calculating observables involving mesons and baryons. Engage with advanced topics in theoretical particle physics designed for postdoctoral fellows and mature PhD students with a strong background in quantum field theory.
