Energy Operator in Particle Physics and Quantum Field Theory

Explore the energy operator's role in particle physics and quantum field theory through this comprehensive conference talk. Delve into the field theoretic framework for measuring energy flow in collider experiments, focusing on the energy-energy correlator (EEC) proposed over four decades ago. Discover the attractive theoretical properties of the energy operator and learn about the recent resurgence of experimental interest in this measurement. Gain insights into the renewed focus across various domains, including formal quantum field theory, QCD and its phenomenology, and particle physics and nuclear experiments. Survey recent progress in these areas and understand the fruitful interplay between theory, phenomenology, and experiments in advancing our understanding of energy operators and their applications.
